When converting <br>s to our preferred <div> style in fixContainer,
we don't want to use the default block style as that may change the
visual output. We always want to just use a basic <div>; the only
purpose is for line breaks.
This makes inline node detection count the TIME element as an inline element.
This was causing <br> to be inserted into a TIME element incorrectly via fixCursor.
* Update the path after making the changes, so UI buttons can update correctly.
* Focus the editor on completion, to match the behaviour of other commands.
* Merge all the gathered text nodes if they're adjacent, so we have a normalised
result.
Just return a boolean for the TreeWalker filter fn. This diverges from the spec,
but since the goal of this implementation is not to fully implement the spec
and we're never going to use a native implementation, this doesn't matter and
the code is easier to read when the function is just returning a boolean like
any normal filter function.
* Hit tab to increase list depth, or call increaseListLevel method.
* Hit enter on a blank item to decrease list depth, or call decreaseListLevel method.
This is now an instance method, whereas before it was global. Annoyingly, we
need to access this from from within fixCursor which has no reference to the
RTE instance itself (and it would be a pain to pass one down). For now, just
referring to the global `editor` variable if it exists (i.e. if the script
loaded in an iframe). Need a better solution longer term though.
* If you load the squire.js script into a top-level page rather than an iframe,
it will add a Squire constructor to the global scope.
* The Squire constructor can be used to instantiate multiple instances on the
same page without having to load/parse/execute the full code every time.
* For each instance, create a new iframe, then call `new Squire( document )`,
with the document node for each iframe.
Won't throw an error if called on a node that is not part of a document, but
will now instead return the path from whatever the root element is down to the
node.
