Current Behavior

After typing for +2 hours a task related with the monkeytype tab started using all cpu resources available to it.
I do not know if it is reproduce able simply since it took one hour before i noticed a slight input lag and chalked ti up to slow internet. After 2hours I noticed severe input lag and high cpu usage.
I kept doing tests for 2 hours and swamped between tabs from time to time

No source file, test, or entry point is named. First reproduce the reported long typing session in Ubuntu 24.10 with Waterfox 6.5.7 while profiling CPU and input lag. Done means identifying a reproducible cause and confirming that extended typing no longer causes severe lag or sustained high CPU usage.
