We noticed that the MWTemplateDialog class is reused by the VE citation dialog and our changes to it should be reviewed and possibly adjusted for that context, as well as any other dependent context.
[ ] Make citation dialog work with the sidebar always open (aim to use most trivial fix). Note: Some of this code is implemented as a VE plugin in the Cite extension.
[ ] Investigate other dependencies (Signature Tool, anything else?) and what is reused there.
Discussed in [[ https://docs.google.com/document/d/1Fj5ljAEtb_bEUeK-hMb3KzVzGohopp9WCakVnTar5Tc/edit#heading=h.7scc696rzskw | story time ]].
== Outcome ==
It was possible to carry over all new sidebar behaviors, while leaving the old workflow unchanged.
There are no other subclasses of either `MWTemplateDialog` or `MWTransclusionDialog`.
