When editing in visual mode Firefox (and perhaps other browsers, too) doesn't break lines after the arrow that is used to display a linebreak. This can cause a display very differently from the normal page.
Steps to reproduce:
- Look at https://de.wikipedia.org/wiki/Hilfe:Bilder. There is a box just above the TOC "Stichwortverzeichnis", which breaks into multiple lines. (Make the window smaller to get at least three lines for most obvious result in the next step.)
- Open the page in VE in Firefox.
Expected result: The box looks similar.
Actual result: The line only breaks at the reference, causing the box to overflow.
Note that the entries all use white-space:nowrap and are separated by linebreaks.
I didn't test other browsers, but from experience I wouldn't be surprised if this only happens in Firefox.
If possible, a <wbr> or some CSS should be used to allow linebreaks after the arrow.
