…tnet#33071) App crashes because of changing a shared Drawable on the fly. I found out it is the SearchBar. It only happens on Android and in large apps with lots of screens. Unfortunately I can't reproduce it in the TestSuite. But by reading the docs of Android this crash is common and caused by changing a Drawable which is still referenced. With a custom SearchBarHandler the issues is resolved. ```Backtrace (top frames): #00 pc 00000000006b8694 /system/lib64/libhwui.so android::getRootAlpha(_JNIEnv*, _jobject*, long) +4 #1 pc 0000000002256c90 /memfd:jit-cache (deleted) art_jni_trampoline +112 #2 pc 000000000223bc4c /memfd:jit-cache (deleted) android.graphics.drawable.VectorDrawable.-$$Nest$smnGetRootAlpha +108 #3 pc 000000000223bb20 /memfd:jit-cache (deleted) android.graphics.drawable.VectorDrawable$VectorDrawableState.getAlpha +144 #4 pc 00000000025c50e0 /memfd:jit-cache (deleted) android.graphics.drawable.VectorDrawable.getAlpha +128 #5 pc 00000000025c4f9c /memfd:jit-cache (deleted) android.graphics.drawable.VectorDrawable.getOpacity +124 #6 pc 00000000025c1ea8 /memfd:jit-cache (deleted) android.widget.ImageView.isOpaque +152 #7 pc 000000000227979c /memfd:jit-cache (deleted) android.view.View.invalidateInternal +428 #8 pc 00000000025c4790 /memfd:jit-cache (deleted) android.widget.ImageView.invalidateDrawable +256 #9 pc 000000000224419c /memfd:jit-cache (deleted) android.graphics.drawable.Drawable.invalidateSelf +156 #10 pc 000000000260e710 /memfd:jit-cache (deleted) android.graphics.drawable.VectorDrawable.setTintList +192 #11 pc 00000000025d0094 /memfd:jit-cache (deleted) **android.graphics.drawable.Drawable.setTint +148** ``` ### Description of Change - Changes tinting of Androids SearchBar to unified setTint instead of setColorFilter - Mutates the drawable before setting the tint. ### Issues Fixed Issue is fixed with a custom handler for now.

GitHub automatically converts '#1', '#2' etc. to issue/PR hyperlinks. In comment scripts, 'Attempt #1' becomes a link to issue #1, which is confusing and incorrect. Fixed by escaping the hash: 'Attempt \#1' which renders as 'Attempt #1' but without the hyperlink. Updated: - post-try-fix-comment.ps1: Escape all Attempt #N references - post-write-tests-comment.ps1: Escape all Attempt #N references

GitHub treats '#1', '#2' etc as hyperlinks even when escaped with backslash. Changed to plain numbering without # symbol: - 'Attempt #1' → 'Attempt 1' - 'Review #1' → 'Review 1' Also ensured all </summary> tags have blank lines after them for proper markdown rendering (already correct in most places). Updated all scripts: - post-write-tests-comment.ps1 - post-try-fix-comment.ps1 - post-pr-finalize-comment.ps1

…es (dotnet#33963) <!-- Please let the below note in for people that find this PR --> > [!NOTE] > Are you waiting for the changes in this PR to be merged? > It would be very helpful if you could [test the resulting artifacts](https://github.com/dotnet/maui/wiki/Testing-PR-Builds) from this PR and let us know in a comment if this change resolves your issue. Thank you! ## Description Adds rule #2 to the Git Workflow section in copilot-instructions.md: **When fixing CI or amending an existing PR, commit directly to the PR branch.** Do not create a separate branch off a PR branch — the PR branch already IS a feature branch. Creating a new branch means CI will not run on the PR, defeating the purpose. Also adds a code example showing the correct workflow (`gh pr checkout` → commit → push). ## Motivation Copilot CLI was incorrectly creating separate branches when asked to fix CI on existing PRs, because rule #1 ("never commit to main, create a feature branch") was being over-generalized to PR branches. This caused wasted time since CI only runs on PR branches. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Shane Neuville <shneuvil@microsoft.com>

Description of Change
Refactors the code to entirely get rid of
MeasureInvalidated.Still, keeps in place the current shell layout manager logic, which is now being triggered (properly) only during
layoutSubviews.
