I am also happy problem with this issue. Pasting 4000 lines into a contentEditable div takes about 5 seconds.
For the time being, I am looking for a workaround if anyone knows any.
PS. CodeMirror seems to do it almost instantly!!!?
Happy to take a patch in nightly; if it seems low risk enough please feel free to request uplift to 65 beta.
Is this still the case? Pasting takes less than a second on my machine.
