  Handle clicking links more than once in Observer's "Expanded term"

OTP-15980

ErlSubBin is a large struct that often dwarfs the region of memory
it points at, and it's common for them to refer to a ProcBin which
must be kept around as long as the SubBin lives, using up even more
heap space and keeping the referenced binary alive regardless of
how small the sub-binary is.

This reverts commit 425889ba69b69a9b6fb14bfbef121d51b78e853a.

When looking at an "expanded term" in Observer, such as the state term
of a supervisor process, all pids are turned into clickable links.
However, without this change, you could only follow one such link; any
further clicks would be ignored.  Fix that by ensuring that the
cdv_html_wx process holds on to its state.

This reverts commit 0118046f9bda8dcf3594184fa439b79267db8017.
