Sample count Editor field scrubbing is heavy and inconsistent

1. Open any project
2. Go to the Lighting Window
3. Try to scrub the sample values
4. Observe that values are not consistently scrub-able, and heavy when scrubbing between values of 2.

Reproduces on Windows, MacOS, Linux.

NOTES:

• The Linux Editor makes it so you can't scrub through values at all, since when you wrap around the display left to right the Editor thinks you dragged right to left.

• Pressing SHIFT helps, but only for low sample values. Above anything ~1024, the same problem arises.
