On some websites, like this one: https://vistaserv.net/blog/90s-fonts-modern-browsers, WebKit puts some large spaces in the middle of a paragraph. If I select the text the spaces go away and WebKit lays it out like it should be.

The font doesn't support the space character, so we're falling back to LucidaGrande for that character.

I'm looking at this bug now.
Comment 5 Myles C. Maxfield 2020-07-21 23:32:58 PDT 
Disabling simple line layout fixes this.

I haven't looked at the code yet, but the test reduction makes me think it is a collapsed whitespace width caching issue in the fast codepath.

I already have a patch on this (see bug 211680)
