Ore UI slider block's center line Do Not Align With Scale Marks

The OREUI has sliders with marks, but is the mark’s position the TRUE position of the slider block indicator’s centre?

Check the picture below.

Pic.1 The in-game outlook of the slider;

Pic.2 What i want to metion in this report;

Pic.3 This unalignment might be annoying depends the mark amout, like in this pic shows.

Steps To Reproduce

1.Open an OREUI menu, and find a slider with marks;

2.Interact with the silder, and see where the sliding block indicator moves.

Expected Result

Method A) The block’s centre is aligned with each mark position, except that in the two egde, the block’s border aligned with the slider’s border;

Method B) The mark position is redesigned, unequal width, and goes like “----|--|--|--|----“

(but might have art problems when the marks are too much, like Pic.4, since there’re only pixels' wide between marks, and it’s not pleased to see a way-too-bold edge mark)

Method C) The block indicator can move more closer to the silder edge.

Method D) I believe that mojang team has better solutions than me.

Observed Result

The block indicator is just not perfectlly align, which is so annoying!
