[tidy] Fix bdi formatting

[behnam]

Looks like the tidy tool coming with Mac does not allow overriding the type of a known tag, like bdi.

For the latest tidy development, I have filed an issue here: htacg/tidy-html5#616

If we want to get the right formatting with the existing tool, we have to replace our <bdi> usage with <span style="unicode-bidi: isolate;">.

Ouch. Much better would be <span dir="rtl/ltr">. We could add RLM/LRM for Edge.

Btw, for those numbers, do we actually need to isolate though?

Wait, do we have a problem with Edge right now?

And, I'm not sure what solution you're suggesting here. Should we replace bdi with span tags? Would you please elaborate?

Yep, otherwise a list of ANs with commas in-between with result in an RTL list.

Another solution is to only list these in a table, in separate cells, instead of the running text.

Posted a stable solution here: #145

What do you think? Should we land that?
