This might be an edge case, but the following STRs might also reveal a weak spot in the code base that's worth fixing. So, I am filing this anyway.

STR
1) Open DevTools and select the Console panel
2) Generate 1M logs and wait till the panel crashes.

Test case coming...

This might be an edge case (generating 1M logs), but the STRs might reveal a weak spot in the code base that's worth fixing. So, I am filing this anyway.

STR
1) Load http://janodvarko.cz/tests/bugzilla/1763780/
2) Open DevTools and select the Console panel
3) Generate 1M logs and wait till the Console panel crashes.
