We copied all html attributes to html_attributes from AXNodeData here.
Because AXNodeData has the fields, html_attributes, string_attributes, and so
on, if we copied several html attributes which doesn't need modification from
original attribute values to string_attributes or others again, I think it's a
redundant work and consumes spaces.
WDYT?

Absolutely true.

I think we could save even more space by only copying the html attributes we
will ever need. But let's save that for a future change.
