A critical error has occurred

Bug Description

A critical error has occurred when pasting a long string into Test string textbox. Possibly same issue with the Patten box.

Reproduction steps

Select ECMAscript Flavor
Use pattern /\p{Emoji}/u, but I suspect any simple pattern will reproduce it.
Continually copy a long string into the the Test string textbox.

Expected Outcome

There should be limit to the Test string and the page should not crash.

Console log:

Uncaught TypeError: Cannot read properties of undefined (reading 'length')

I am unable to reproduce this. Can you show a video or something?

Sure, note that the string copied was just a random generated string from alpha-numeric character set: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 This time using Edge version Version 113.0.1774.42 (Official build) (64-bit)

This looks like a bug in CodeMirror.... It seems it cannot handle that large texts for some reason.

Can this still be reproduced?

I also encountered this issue while copying long text

Anyone run into this again?
