Why is it only about user scripts? How media wiki script are going to be updated?

I also have it, the button works, only the pencil is missing

@Aklapper I changed the task to be more adapted to newbies. As of Wikibooks, I created the project there myself: https://en.wikibooks.org/wiki/Wikibooks:Correct_typos_in_one_click

@Aklapper the backlash was needed when I ran it since it had space in the file name, I changed the description to instruct to use file name without spaces so backlash is no longer needed.

@Aklapper thanks for the instructions, I edited the task. Let me know if something is still missing.

@Aklapper anything missing?

1 Download "Articles, templates, media/file descriptions, and primary meta-pages." from https://dumps.wikimedia.org/enwikibooks/20191120/
2 Running the program requires compiling, which can be done by gcc command. I'm not sure about the students prior knowledge in coding.
3 Creating the project page can be done by searching "Wikibooks:Correct typos in one click" inside en.wikibooks.org and clicking on the red link of "Wikibooks:Correct typos in one click" on the top of the results. It is preferred to edit on Wikibooks with an account, which can be created by clicking "Create account" on the top menu.
4 enwiki is en.wikipedia.org and the same project there is at https://en.wikipedia.org/wiki/Wikipedia:Correct_typos_in_one_click

The task requires two things: scan for typos in dumps and user interface to correct in one click.
Steps:
1 downloading the c program, word list and dump of enwikibooks
2 running the c program to scan the dump file for the typos on the list
3 copying user script from enwiki to enwikibooks
4 creating project page for the output and adjusting the script to run on that page
5 testing by correcting typos using the new buttons the script adds

"each revision must have a "main" slot that corresponds to what is without MCR the singular page content." (Requests for comment/Multi-Content Revisions)

I am using MediaWiki 1.33.0
You can see the error here: https://meaning.wiki/h/index.php?title=%D7%90%D7%A7%D7%98%D7%95%D7%A4%D7%A8%D7%96%D7%99%D7%98&action=edit
I'm not sure how should I check full stack trace of it.

The bug just happened on my Galaxy S6.

Just bought Galaxy s6, Android 6.0.1, Chrome acts OK on this phone, couldn't reproduce the bug.

The phones I tried are 4.4.4 and 6.0.1

Chrome on laptop and IPad didn't have this bug.

I tried 3 random phones in three random articles and all of them made this bug consistently. Can't you find an android with Chrome and try it yourself?

Yes.

I tried safari and firefox and it didn't happen.
I tried Chrome on Samsung J5 and One Plus 2 and it happened.
I tried Chrome on IPAD and it didn't happen.
I tried Chrome on my laptop with m. in the url and it didnwt happen.

On android, mobile view, editing any wikimedia page, using backspace or cut for deleting text, makes the screen scroll up to almost top of page. For example, I try to edit https://en.m.wikipedia.org/wiki/Ringwoodite top paragraph, backspace to delete the dot on the end scrolls me back to | class... in the infobox.
