Description tech4him 2017-04-12 12:23:42 PDT 
Here is an example: http://codepen.io/tech4him1/pen/mmdMVX

If I set font-size to "calc(1.25em + 0.25vw)", it will calculate properly on page load, but after that it will not update if the page is resized. If I instead set font-size to "calc(125% + 0.25vw)", it works fine.

Bug 87846 fixed this for regular values, but not for all combinations in "calc()".
Comment 3 Ahmad Saleem 2022-10-01 15:04:35 PDT 
I am not able to reproduce this issue in Safari 16 using CodePen from Comment 0 and the resizing of window does not trigger any change in the font size and it is similar to Chrome Canary 108 and Firefox Nightly 107.

Appreciate if someone else can confirm and mark this bug accordingly. Thanks!

Closing based on Ahmad's testing.
