Entries in Page settings / Languages don't have dir attributes for the link text. It leads to bidi issues for RTL languages.
- Go to an article with a langlink to Hebrew, for instance. Here's my favourite: [[en:August 3]].
- Open the VisualEditor.
- Go to Page settings / Languages and scroll down to 'he'.
- Link text reads as "3 באוגוסט", but it should read with "3" after Hebrew characters (reading left-to-right, of course; in the beginning of the string, if right-to-left).
