On the page on mediawiki.org https://www.mediawiki.org/wiki/Manual:ISBN (check action=history) VisualEditor keeps removing certain characters after I try to use it to make changes to the page. An example is given at https://www.mediawiki.org/wiki/VisualEditor:Test
Reproduction steps:
- Set up a new page using the following code
<space><space><space><url><apostrophe>
<newline><space><space><space>
example text1
example text2
Where <space> is one hit of the spacebar and <url> could be any URL
- Modify other places in the text, such as "example text2".
- See the first character in "example text1" get cut off.
- Modify "example text2" again and see "example text1" get cut off again.
