Appreciate the brisk responses, I really should've brought this up sooner!

Wikitext editing on mobile is a pain

And as someone who primarily edits on mobile with wikitext, I really have to agree, but this will certainly help!

@Erutuon Indeed it's not yet working; do you happen to know the difference between hitting the "edit" button on a new page versus hitting the "edit full page" button? One would think their behavior should be identical so I would imagine there might be some difference causing the issue.

The duplication/snowmen issue seems resolved, although now I have to hit the backspace button approximately a million times before it starts actually deleting if I start on the last blank line 🤷

@matmarex Yes, this still happens. I tried it again and got the same behavior on https://en.wikipedia.org/wiki/User:Matma_Rex/T262515

Thanks for testing this so quickly, though that is interesting that it did not occur. The snowmen replacing references may very well be a separate bug that this one just happens to cause as well. In either case, I just tried on your page and it occurred again (duplicated "Test" with two snowmen after it). I can send a screen recording of it happening if it would be helpful?
