Follow-up from "Keep IDE RightPane views alive"

Description

The following discussion from gitlab-ce!21980 should be addressed:

• @pslaughter started a discussion: (+3 comments)

  Would it make the logic simpler if we just kept all of the sidebars alive? 🤔

  This was my original intent. Unfortunately some views are not in a position where this is possible.

  Safe to keep alive:

  • merge-request-info simply presents some Vuex state, so it is safe to keep alive.
  • pipelines initializes a polling routine on mount, which is safe to keep alive.

  Not safe to keep alive:

  • jobs-detail fetches getTrace() on mount, which is based on the currently selected job. If this views was kept alive, but the job changed, it will still show the old trace. Also, (for some unknown reason) this view seems to blow up when it is kept alive but not active. 🤷
  • clientside similarly, this component initializes on mount based on the current files.

  WDYT, of creating an issue to address the not safe components, with the intention of keeping all the sidebars alive?
