When reviewing a PR and adding a code comment with multiple lines, refined github causes a slowdown that results in a typing appearing on the screen a second or so after keys are pressed.
I ran the profiler on the page and identified that each keypress is calling the fitTextArea() function and takes ~5ms.
Turning off the fit-textarea feature resolves the problem and typing is not delayed any more.
