Environment/Versions

• GIMP version: 2.99.16, Flatpak
• Operating System: Linux

Description of the bug

Single left clicking the tool sliders and opacity sliders should just set the slider position and enable dragging.

At the moment, if you happen to left click the right end of the slider, the numerical input is activated in a buggy way.

Reproduction

Is the bug reproducible? Yes

Reproduction steps:

1. Left Click the number end of a slider
2. Number entry gets focus
3. Slider not draggable

Expected result: Slider active and draggable

Actual result: Number input

Additional information

Right click, or middle click, or double left click, to highlight all the numbers so that entering 50 would set the slider to 50%, pressing return or clicking elsewhere to finish.
