paste infotext cast int as float

[w-e-w]

Description

when casting the infotext string to it's corresponding element type the element type is determined by the default value saved in ui-config.json

this causes issues in one particular case

if a slider is implemented with a value range of [0, 1] step size of 0.1 default value 1
if the developer set sleep value to 1 and not 1.0, a integer one will be saved to ui-config.json,
later when trying to perform paste infotext, becaue the value is a integer the value will be cast to a integer, but in this particular case it should be a float
this will result in an incorrectly value beeing applied to the UI

this is a real issue that I have run into just now
when verifying an extension and decide to take a little bit of time to implement infotext copypast for extension
