TC 64bit: Cursor border color not set in "Define colors by file type"

[StatusQuo]

Configuration > Options > Color > Define colors by file type:
When using a blue panel background the cursor position in configuration dialog is almost invisible in 64bit TC.

OK in 32bit TC: The selected line has a dotted border colored like the selected text color of the line.
In 64bit this border is solid and always in blue color (hardcoded?).

Identical in all 64bit versions (since TC 8.00). Quite old, but I couldn't find a thread about it.

It's not hard coded, it uses a system color. 32-bit adds dotted "current file" automatically, 64-bit doesn't. I will add it myself.

Confirm fixed in TC 9.51 RC3, thanks.
