Changing current-value does not update as expected, but current-index works fine.

[DavidVentura]

Bug Description

If a combo-box is manually updated, then updating it from rust will not be visible on the UI; however changing screens (??) makes the rust-side work until it's manually updated again.

I think this is just an issue with 'current-value'. If instead you change 'current-index' it will update as expected. I've changed the title so we can track fixing the issue with 'current-value'.
