press down arrow key after some time getting page unresponsive error

In code mirror editor, when navigate the cursor with down arrow key getting page unresponsive error in html

You’re going to have to provide a bit more context if you want a useful response here. There is not, I am pretty sure, a general problem where pressing the down arrow hang the library.

Issue facing chrome. version of code mirror is 3.19.0 .Am using code mirror in HTML, When navigate the cursor by pressing down arrow key in keyboard after few lines screen got stucked and getting page unresponsive error. And not getting any errors in console as well.


That version is almost 10 years old. Upgrading to 5.65.16 might be a thing to try first.

ok thank you. i will try one and let you know if i face any issue.
