I can type a certain amount of text into a Confluence Comment field in response to an article posted there. At a certain point near the bottom of the text area box I can no longer see what I type. Each press of the keyboard will jump the display of text down then auto-scroll back up so that I can't see what I typed. This forces me to use an external tool to type up my full comment and then copy/paste it into the Comment box in Confluence... a pain. At that point I still don't see all the text. If I arrow down to the text that is out of sight, it jumps down for a split second then auto-scrolls back up, hiding the display of that lower text. If I Preview the comment I then see it's all there. I can post the comment and it's all there. But in edit mode, it's broken. There needs to be a scroll bar for oversized text content and a grow-box-size handle in the bottom right corner of the Comment text box to increase the box size displayed.

I made a screen capture movie of this issue in action. Hope this helps illustrate the issue: http://screencast.com/t/r4e17crdacc

Workaround

Uninstall the "Confluence browser fixes" plugin or "Confluence editor height fix" plugin from versions that already have these fixes bundled.
