1717621 - `text-transform: uppercase` breaks letter-spacing when ß is replaced with SS

Status: RESOLVED DUPLICATE of bug 393766

(Core :: Layout: Text and Fonts, defect)

Description

Attachment: uppercase_ss_letter-spacing.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:89.0) Gecko/20100101 Firefox/89.0

Steps to reproduce:

Apply text-transform: uppercase to a text with a small German "ß" (sharp s).

Actual results:

"ß" is correctly replaced to "SS", but CSS letter-spacing is not applied between these 2 characters.

Expected results:

letter-spacing should also be applied between SS. This works correctly on current Chrome and Safari.

Interestingly chrome gets the text spacing right but the selection bounds wrong...
