[bug] Writing Exchange unusable in Safari

The entire page freezes for about a second every time a key is pressed while in the Correct Writing text box, making it completely unusable. The only way to use the feature in Safari is to copy the text into an external editor

This happens to me too but they told me they couldn’t reproduce it and thus could do nothing about it.

Thanks for reporting, I asked our team to look into it again and try to figure out what’s going on.
