Resizing the Script Editor is slow for large scripts

On Windows.

If you open a large script, eg revidelibrary, resizing the script editor is slow and does not live resize. It's fine for smaller scripts.

This engine issue in the field control affects all platforms. It's due to the field re-wrapping and re-laying-out all its contents whenever it changes. I came across it during my work to improve script editor performance...
