Adding mention or emoji inline (:name) switches text direction
To reproduce, switch to RTL, and add an emoji by typing : and selecting one from the dialog selection box. The direction will switch to LTR and the line will be aligned to the left.
Turns out this is an old issue I reported earlier with textcomplete and mention.
The following pull fixed markdown, but not mention: https://github.com/julianlam/nodebb-plugin-markdown/pull/107
We should reopen the issue: https://github.com/NodeBB/NodeBB/issues/7457
To recap, mention returns a string @ + userslug, and that confuses the editor. It should return html with direction / alignment attributes.
Update:
I removed HTML support from textcomplete.contenteditable that I had earlier to solve RTL issues with Redactor. Now mention and inline emoji work well. Using text also fixes https://github.com/NodeBB/nodebb-plugin-composer-quill/issues/79.
As for textcomplete.contenteditable: The command that was making quill reset the direction is "range.deleteContents();". That command stems from a PR for providing HTML support. See here: (https://github.com/yuku/textcomplete.contenteditable/pull/3)
Since HTML insertion is not supported by composer, and since we are dropping Redactor, going back to text is the best solution.
I did however keep the changes from the mentioned PR that allow textcomplete to work with Safari. @julianlam I do believe Safari related support should be integrated to the core, for the benefit of all other users.
Feel free to close this issue when appropriate.
