Additional notes for the bug I have reported.
I guess the problem is in the definition of \AA:text in mahml.4ht and mozilla.4ht. There is a \Configure{$} in the definition ensuring that math between $ work but no \Configure{()} for math between \( and \). So the bug maybe fixed by adding \Configure{()} with similar arguments as those of \Configure{$} but adding two $ to enter and exit math mode. Therefore, I suggest the following patch, which seems to work for me. To avoid repetition, I have introduced a new \Configure{$,()} for simultaneously configuring $ and (). (I am not sure how to handle the different number of arguments of these configurations.)
