[Bug 2007652] Re: [SRU] PWA don't launch as applications, just another chromium window

[Robie Basak]

SRU review for Noble: in progress.

The upload references 17 bugs and since they all follow the regular SRU
process, there's no "tracking bug" as such where I can comment on the
review as a whole. This is a shortcoming in our current workflow. I
decided to arbitrarily choose the lowest numbered bug to comment
generally as a workaround, which is this one. But to avoid clutter for
an exceptionally large SRU with various workflow issues that need
ironing out, I'm doing the entire (lengthy) review in a Google Doc
instead, and just linking to that from here:
https://docs.google.com/document/d/1Tmopo83MVPjefk5aiuZ8ntZgT9t0IenHfdeNuN7IVoc/edit

If others need to comment on this SRU review generally and can't
communicate out of band or in the Google Doc, I suggest doing it here.

Bug description:
  Impact
  ------

  When converting from deb to snap package of chromium, progressive web
  applications (PWAs) launch just as another window of chromium and are
  not recognized as separate application by the window manager (for
  example when switching using Super+Tab) or dock (grouped under
  chromium windows).

  This strikes users as a regression (as it is).

  Test case
  ---------

  *Install the package.
  *Log in to Ubuntu desktop.
  *Start Chromium.
  *Go to a site that offers PWA to install, e.g. earth.google.com.
  *In the right end of the address bar, click the icon to install the PWA.
  *The PWA opens in a separate window.
  In this first launch it may be that the PWA is not yet recognized as a different application by the Gnome Shell, if this is the case, close the PWA and open it again.
  *Verify that the PWA behaves as a stand-alone program, namely insofar as it:
  ++can be found by pressing Super and then typing its name (e.g. 'earth' if you installed Google Earth).
  ++launches when thereby clicking that launcher.
  ++does not share Chromium's tab group in the alt-tab switcher.
  ++does not share Chromium's launcher icon in the dock (i.e. the launcher bar that by default is flush to the left edge of the screen).

  Regression potential
  --------------------

  Regressions may arise as incorrect window grouping in the alt-tab
  switcher or in the dock for desktop applications.
