Characters get mixed up while typing
I have an extisting template setup with about 80 lines.
After an existing header comment, like "# this is the main template", I entered two blank lines and started typing "page =" (fast, like typing letters or whatever).
The results I got in t3editor were "age0p" or "age=p" or "ge=pa", so the characters of "page" and the "0" (shift-0) got mixed and not recognized correctly. Maybe the JS event listeners were to slow.
Occours in Firefox 184.108.40.206, could not reproduce in IE7 and Safari3.
