SQL Developer

If Preferences > Code Editor > Display > Show Whitespace Characters is checked, and I type the following in SQL Worksheet:

--A[tab]B[space]C

It renders with two spaces between B and C. The first one is a blank space without the light dot character used to signify a space character, and the second space is filled with the dot character. The caret is then blinking before the C instead of after it:

--A[tab]B[space][dot][|]C

Further selection actions and editing in the region produce "corrupted" results. I've tried changing fonts, but there was no change to the behavior. Multiple tabs before the B produce multiple blank spaces immediately after it, and when placed at the end of the line the caret is then shown another space to the left of the C:

--A[tab][tab]B[space][space][|][dot]C

If I turn off Show Whitespace Characters the rendering immediately corrects, and caret placement, selection action, and editing behaviors all work as expected.

This is observed on OS X with both the Mac OS X and Oracle/Fusion Blue look and feels.
