Summary WebKit can strip lang attribute when deleting a line break and change font

Apparently lang="en-us" can affect the way font-fallback works and cause the appearance of text to change. Reproduction steps: 1. Open the attached email (which appears to be composed by Microsoft Outlook/Outlook Express) 2. Delete the line break before second to the last line. Expected result: The blank line is removed and the all text maintains the same appearance. Actual result: The blank line is removed but the line before which the line break was removed changes its appearance.

Created attachment 193189 [details] Demo for Chinese/Japanese This bug is particularly bad when Chinese and Japanese are mixed because unicode uses the same code point for multiple characters that are considered distinctively different in those two languages.

@rniwa - It seems that this is not longer reproducible. I am not able to reproduce this bug using Demo for Chinese / Japanese, Safari Technology Preview 160 does not change the font and also matches similar to Chrome Canary 110 and Firefox Nightly 110. Let me know if I am doing something wrong. Thanks!
