can we do this without the debug flags? there's been lots of times now that I am trying to debug something in WK without debug symbols and just wishing I could convert from AX tree > HTML

worried that we're setting this property on the main thread. I guess we'll be ok because the AX thread is also blocked. can you think of any other issues with this?

String().isolatedCopy() is the same as Striing().

Done.

It could be a problem if this method is called on the main thread and there are other isolated object methods being called on the AX thread. This shouldn't happen though. Let me see if I can add an assert to ensure this in debug.

The problem with the assert is that if you break on the main thread during debugging with isolated mode on, then you cannot call these methods. You can only call it on the secondary thread. Would that be ok?

I think we're probably OK because the secondary thread will be occupied while the main thread modifies the property map, but its not really air-tight.
