Slider handle position is offset when sliders "showMixedValue" value is changed

Reproduction steps:
1. Open the attached project
2. In the Scene window lower right corner check and uncheck one of the checkboxes in the overlay window

Expected result: The slider handle stays in the same position
Actual result: The slider handle disappears or is offset to the right side

Reproducible with: 2021.3.8f1, 2022.1.14f1, 2022.2.0b6, 2023.1.0a8

Reproducible on: macOS 12.5

Couldn’t test: 2020.3.38f1 - there is no Overlay functionality

Note: The overlay stays responsive and the values can be changed, but the handle is invisible/offset if it is used.
