Increase Contrast = White Cursor in Scratchpad

As I reported here, if Increase Contrast is selected in Accessibility Preferences, the cursor for the scratchpad is white no matter which background colour you choose. If you use the default background colour, the cursor will be invisible.

Unfortunately this seems to be an Apple bug - it seems to assume that because the scratch pad uses a black translucent window, the text caret should contrast that rather than the text background. Scrivener doesn’t touch the caret colour at all in the scratch pad area. I’ll try setting the caret colour explicitly to see if that helps.
