Subject: [PATCH] Work around crash in wxStyledTextCtrl under Mac

When not using double buffering, double-clicking to select text in the
control results in crashes.

Avoid this by using double-buffering under Mac, even though it shouldn't
be necessary.

This reverts the changes of cb799483b7cf19f0e2db5df857be5e79dafab38d
under Mac.

See #18085.
