SE 11.0.2: paren matching highlighting worked properly.
SE 14.0.2: paren matching highlighting works... but the background color fails to show when the paren is single-character, and shows ok when the paren is multi-character.
For example, in C/C++:
#if and #endif (multi-character symbols) are highlighted correctly (foreground and background color are both correct as setup in Options, just like I colored in this post).
{ and } (single-character symbols) are highlighted incorrectly (foreground color is ok, background colour does not show... see attached pic... the paren at the cursor has no background color).
