Ligature fonts fail "Visible label is part of accessible name " (2ee8b8)

[WilcoFiers]

Ligature fonts can be used as icons, things like this:

<span aria-label="Remove" style="font-family: \'LigatureSymbols\'">delete</span>

In a case like this, "delete" should not be treated as visible text, as the entire word is replaced with an icon.

1. I am not sure what you mean given that I see no difference in rendering between this element with or without the style attribute (Chrome, Edge, Firefox). Notably, I can select individual letters from the element with the style attribute and don't understand what you mean by " the entire word is replaced with an icon".
   It might be due to a font not being installed on my computer, which at the very least show that this issue is tricky (it depends on what's on the user's computer).

2. Would adding an assumption to the rule about CSS/font not hijacking the content be enough? Similar assumptions are already added as part of the update to this rule.

I'm not going to put this in an assumption, because this scenario isn't theoretical. You can find an example of this in the icons in the nav on news.google.com.
