This is a problem we're experiencing on stage due to a bug in paragon. This is intended as a temporary fix until we can dig into why this is happening in paragon. But basically the Context for the SelectableBox is missing a provider in paragon. The short-term fix is to copy over paragon's selectablebox component and fix it. This is done so that our quick fix doesn't break anything else in paragon for now or cause any unexpected issues.
This is a refactoring for a part of the ReactStateXMLParser. I wanted to use functions that are more generic and not just handle a list of edge cases. So I encapsulated the operation that was done in this part of the code to a function `findNodesAndRemoveTheirParentNodes` which is more generic and could be used for different operations.

This fixes a bug where the editor was deleting the OLX tag when editing in the simple editor and then saving.
Also the description was being converted to em for the simple editor, but then not converted back. However, the xblock renders label and then em in reverse order for some reason.
To fix it, the em gets converted back to description now, but not for every em tag (added a class "olx_description" for the tags that should be converted).
* fix: video upload page layout fixes
* fix: video editor thumbnail fallback icon colour and size
* fix: video uploader close button go back instead of closing app
Change the video uploader close button to always go back in navigation history,
and change the gallery to replace its location with the video uploader's when
automatically loading it due to an empty video list, so that when the uploader
goes back in the history, it goes to what was before the gallery.
* fix: video editor spinners vertical alignment
The Editor component uses the pgn__modal-fullscreen class to be fullscreen,
but it is not structured like a Paragon FullscreenModal and the fullscreen
positioning style is not applied correctly, particularly in the case where
the content is smaller than the body - a vertically centred component will
be centred to the content size, not to the screen.
Here we directly apply the style that would have applied to the relevant
elements of a Paragon FullscreenModal.
* fix: use trailingElement for video uploader input button
Also styles the button so it looks the same on hover/active.
