Steps to replicate the issue (include links if applicable):

• Go to the lbwiki article "Florent de Berlaymont" (or any other article with formatting that spans multiple lines)
• Click on "Edit article"
• Scroll down until you reach a point, where the beginning of a formatted text segment isn't visible on screen.

What happens?:
The text on-screen is formatted as if the formatting tokens of the text off-screen doesn't exist. E.g. if a text segment is enclosed between [ ... ] and '' ... '', but the leading [ and the leading '' aren't visible on the phone screen, the text segment isn't formatted as a link and as italics; on the other hand, the text that follows the closing '' is formatted as italics.

What should have happened instead?:
The text's formatting should be independent of what portion of the text is currently visible on-screen. E.g. if a text segment is enclosed between [ ... ] and '' ... '', it should be formatted as a link and as italics; the text that follows the closing '' should obviously no longer be formatted as italics.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):
In the two screenshots below, one can see that the formatting depends on what formatting tokens are visible on-screen. This should not be the case.
