Bug 185584 – [macOS] Spelling errors in the middle of an inserted paragraph are not displayed

• Component: HTML Editing
• Status: RESOLVED FIXED

[Wenson Hsieh]

Spellcheck results in the middle of an inserted paragraph of text are not displayed after ending the paragraph.

To reproduce:

1. Paste "Helol wrodl" into a contenteditable div or textarea.
2. Hit enter to insert a newline

Expected: red underlines underneath "Helol" and "wrodl".
Observed: red underlines only underneath "wrodl".

Reproduces on macOS El Capitan using system Safari (possibly reproduces earlier than El Capitan).

Did you mean to put a period between ranges & see?

Should we be running this code in old macOS too? Does that even work?

Hm.. I think typeCharacterCommand should trigger spell checking in the browser too.

I put an emdash (—), but it seems Bugzilla's diff viewer doesn't handle unicode well :/

Yes, I believe so. This fixes an existing bug wherein pasting some text that contains misspelled words will not add document markers for the misspelled ranges. This case is covered by one of the new tests, spelling-markers-after-pasting-sentence.html.

Oh, that's a good point! I'll make it so that we automatically type out the string when opening this manually.
