Steps to reproduce

Go in history of same page
Try to select edit summary

If you select it with first letter of edit summary, you can't select it. If you select edit summary without first letter of it, selecting works. Selecting should works completly.

[ORIGINAL REPORT]
Good afternoon.

I have noticed a glitch that happens when I want to select the edit summary and copy it. It is not possible to select the first letter of it with the cursor from the left, but when is the first letter chosen from the right with another text, the page completely crashes. This happens everywhere with the edit summary (in user contributions, recent changes, page history...), and on all of Wikipedia projects (I tried English, Croatian, Hungarian and Czech Wikipedia, English Wiktionary, Wikimedia Commons). But it happens only on MediaWiki projects. On other sites, such as Wikia, the summary selection works completely normal.

Hi @Moson81 and welcome to Phabricator! You assigned this task to you, do you really want to fix in code this problem?

I do not know how to fix it. I ask if it's possible to fix this problem.

I have taken some screenshots of the problem: https://commons.wikimedia.org/wiki/File:SummaryProblem1.jpg and https://commons.wikimedia.org/wiki/File:SummaryProblem2.jpg

Hmm, yes. I can reproduce this. When user want to select edit summary, if he select first letter it can't select nothing in summary. If he select second letter everything is ok but first letter is still unselectable.

Kizule renamed this task from Wikipedia page crashes in error after first letter of an edit summary is selected to First letter of an edit summary can't be selected.Sep 1 2019, 2:23 PM

Kizule changed the task status from Stalled to Open.

Kizule updated the task description. (Show Details)

Thanks for the clarification.

From Firefox 68 on https://cs.wikipedia.org/w/index.php?title=Galerie_Rudolfinum&action=history (please always provide links!):

This happens because the brackets are pseudo elements in CSS. See for example https://github.com/w3c/csswg-drafts/issues/2894

Hi @AdarshTiwari11, thanks for your interest and welcome to Wikimedia Phabricator! Do you have a specific question?

i have just did environment setup , can you say what should be my first step to start this process

Generally speaking (which is off-topic here, see the link I had posted): Reproducing the problem, investigating it, finding the related code, writing a fix, verifying that the fix does what it should, putting the fix up for review in Gerrit. Basically. :) See also https://www.mediawiki.org/wiki/How_to_become_a_MediaWiki_hacker - thanks!
