This is a follow-up for bug 20324 [1]. Sorry to fill a separate report, I was unable to re-open the old one. The changes in "d" attribute of a glyph of a SVG font wont show up in a text set in the font. One needs to "manually" trigger the refresh, e.g. by mousing over or changing the background color. Please see the slightly modified former test case and a new one (to refresh, click inside the blue square), attached bellow. [1] https://bugs.webkit.org/show_bug.cgi?id=20324

I am still able to reproduce this bug in Safari 15.5 and the test cases show "cone" rather than "abc" or "a" (depending on tests) compared to other browsers (Chrome Canary 104 and Firefox Nightly 102). I am able to reproduce in Safari TP 146 as well. Thanks!

NOTE - This is related to SVG Font, so matching Firefox Nightly 120 and Chrome Canary 120 are not possible since both of them don't support SVG Fonts.
