Height of element changes when ellipses show on a -webkit-line-clamp element with line-height

When there is an element with -webkit-line-clamp and line-height set, the height of the element is different when the text is just short enough to not warrant ellipses vs when the text is just long enough to warrant ellipses.

e.g.
With line-height
No ellipses: height is 44px
With ellipses: height is 42px

Without line-height
No ellipses: height is 38px
With ellipses: height is 38px

I am not able to reproduce the shrinkage of textarea in height using Safari Technology Preview 163 using testcase from Comment 02.

It is reproducible in Safari 16.3 though, can we mark this as "RESOLVED CONFIGURATION CHANGED"? Thanks!

This is an IFC progression (with line-clamp support enabled now).
