Page overload if you paste too much text in the regex box

[Palloxin]

Bug Description

Page and browser (and OS) overload if you paste too much text in the regex box

Reproduction steps

largetext.txt
Paste the content of this file in the regex box.

Expected Outcome

Probably a character limit in the regex box, for stability reasons
Edit: character limit check when text gets pasted

Other details

In the file there are 9.3 milion characters. I somehow pasted by mistake way more than that like 100 and the OS started lagging badly too.
I suggest to put a 100k character limit to the regex box or something to prevent the browser to collapse.
I am not sure if putting a character check limit would make the match time slower; if so please find another solution.

Browser

Firefox

OS

Windows 10

Maybe a character-limit-check ONLY upon the action of "pasting" text.

When you say regex box do you mean the regular expression input or test string textarea?

[Palloxin]

regular expression box.

The string box can take a lot of text, no problem.

I see. I pasted the text you linked in Brave and it chewed up 8GB of RAM, was responsive for a couple seconds, then the tab crashed: Error code: Out of Memory but the OS is fine. I'm assuming it has to do with the fact that I have plenty of system memory.
