When editing a page an author may insert anchors into their content (via
TinyMCE), and wish to link to those anchors from another point in that
page. E.g. creating a table of contents, a "jump to top" link at the
base of the content, etc.
Previously this required the page to first be saved as a draft, then
reloaded before the anchors would show in the list to link to. Now they
are dynamically pulled from the content entered for a more fluid editing
experience.
To reproduce this issue open a page, add an anchor, save the page, go to link to newly created anchor on the same page.
Incorrect result will be the new anchor does not appear. This patch ensures that the page anchors are reloaded.
