1. Open up a page that has resizable textarea field. For example script command or description, audit log details, host description or any other.

2. Drag the text area by the corner to the right outside the popup border and release the mouse.

At this point it's not possible to resize it back.

3. Try to type a long description and reach the far right side of the textarea.

Still not possible.

4. Drop all hope and delete what you typed in text area.

It's not longer possible to get back to previous state and labels are left outside the border on the left size.

5. Try to resize a textarea in JIRA. It's not possible. A trivial thing that could use some improvement in UI, so that textareas are not draggable beyond certain point. For example adding a max-width.
