Description

Description

An example:

#set page(width: auto, height: auto, margin: 1em)

$ V_y != overline(V)_y != underline(V)_y $

test

On reflection, #4695 probably wasn't done the best way, relying on text_like-ness...

Research direction

Start with the example in the issue and inspect the math kerning behavior for overline and underline constructs, using issue #4695 as context. Compare the spacing of V_y, overline(V)_y, and underline(V)_y, then verify that kerning is applied consistently when the decorated character is the base.
