A testcase without glyph from fallback:
data:text/html;charset=utf8,<span style="float: left; font-family: 'Geeza Pro'">%D9%85%D8%AA%D9%86 %DB%B5%DB%B0%DB%B0%D9%87%D8%B2%D8%A7%D8%B1%D9%85%DB%8C%D9%86 %D9%85%D8%AA%D9%86</span>

It looks like both min-content and max-content are wrong in this case:

data:text/html;charset=utf8,<div style="width: min-content; font-family: 'Geeza Pro'; outline: solid">%D9%85%D8%AA%D9%86 %DB%B5%DB%B0%DB%B0%D9%87%D8%B2%D8%A7%D8%B1%D9%85%DB%8C%D9%86 %D9%85%D8%AA%D9%86</div>

data:text/html;charset=utf8,<div style="width: max-content; font-family: 'Geeza Pro'; outline: solid">%D9%85%D8%AA%D9%86 %DB%B5%DB%B0%DB%B0%D9%87%D8%B2%D8%A7%D8%B1%D9%85%DB%8C%D9%86 %D9%85%D8%AA%D9%86</div>

Are we measuring with "fastpath"?  Looks like what would happen if Arabic is not properly shaped.
