To remove the flash on refresh of the topsites list we have to use submitList, however using this too high up in the hierarchy of our listAdapters within listAdapters will cause children to refresh at once. The solution to this is to use submitList lower. Using it in TopSitesPagerAdapter.kt to update the TopSitesAdapter is the way to go. I've also had to use a dummy item for the "removed" Topsite ( with id = -1) so I can manually diff that before using submitList.
The reducer in this middleware assumes the SessionState is always a
TabSessionState which holds the lastMediaAccess. This is true for the
lastAccess long which is a persistent state.
The list of MediaSessionActions however can also come from Custom Tabs
which relies on a CustomTabSessionState.
For now, the temporary fix is to disable this feature by removing the
middleware and no longer adding the last accessed media to the
recent tabs list ("Jump back in") to avoid crashing users while we think
of a real fix.
The change to the function makes it so when the Settings.kt class is initialized, the isDefaultBrowser, which calls the
BrowserCache, won't get called right away. `isDefaultBrowser()` is known to take quite a while on start up on the G5+ (approx
30-40ms).
Apparently, it had been using the wrong mapping this whole time. I can't
wrap my head around fenix's glean wrapper so I'm not sure if this
resulted in bugs or if my change changes the behavior. However, I don't
think anyone is using this probe so I'm requesting to remove it. If we
don't end up removing it, then we can check for bugs/changes in
behavior. This isn't ideal but I'd rather not spend the time on it if we
don't have to.
Github supports a more useful templating system that can provide
hints, descriptions, and simple data validation.
We can try to use this to increase the quality of our bug reports.
