Closes #17216

Description

For some reason Safari does not calculate the correct height from pseudo classes ::webkit-scrollbar. Might be because it is a variable.

Pull request overview

Fixes a Safari-specific issue where the horizontal scrollbar in igx-for-of was not rendered correctly because Safari did not derive a height from the ::-webkit-scrollbar pseudo-element. The fix gives the horizontal helper an explicit height using the existing --vhelper-scrollbar-size CSS custom property (already used to set the vertical helper's width on line 15), ensuring consistent scrollbar sizing across browsers.

Changes:

  • Add an explicit height: var(--vhelper-scrollbar-size) to the %vhelper--horizontal placeholder so Safari renders the horizontal scrollbar at the correct size.
