Percentages displaying inaccurately w/ large numbers

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

This appears to occur for every value I have tested with percentage input (rit., fermatas, Measure width)2. Start a new file

1. Place a fermata
2. Under Properties > Playback set the time stretch to a value
3. Observe the value snap to some other smaller amount (100% for fermatas, 0% for width)
4. Note that the value appears to be updated internally
5. Note that the value properly displays upon reopening the UI element.

Reproduce the issue in a current MuseScore Studio build by changing percentage values for fermata playback time stretch and Measure width, then compare with the latest released version. Trace the UI path responsible for displaying the edited value; done means large percentage values remain accurate immediately after editing and still display correctly when reopening the UI element.
