Change subject: Move dp.src handlers to their respective dom handlers
......................................................................
Move dp.src handlers to their respective dom handlers
* That these cases still remain in the encapsulated content handler
looks like a relic of 8939c692.
* This permits better fallback behaviour when the reuse test fails.
(see the entity encoding change in the blacklisted test).
* The newly failing test is because the case now falls to the figure
handler, which doesn't know about dp.src. That seems acceptable
though, since the output is the same as the html2wt test, where we've
removed the dp.src. Also, we're only adding the placeholder marking
so the content is uneditable. Presumably that means selser will take
care of it.
