• Open https://de.m.wikipedia.org/wiki/IC_4216 in a mobile browser
• Click the edit button
• Switch to visual editor if the source code editor is opened
• Try to add text after the reference that is at the end of the last paragraph

What happens?:
It is not possible to add text at this position. Either the preview of the reference is opened or the cursor disappears.

What should have happened instead?:
It is possible to move the cursor after the last reference and add text.
