Comment 9 for bug 735205

FYI I have always seen this when trying to al-tab away from a chromium window. I however do not use multiple workspaces.
Once there's one icon wiggling, alt-tab does the same to other icons as well, it does not remedy itself unless pressing Super/Esc and various combinations of making the sidebar go away/come back, or by clicking on one of the icons to switch to an app.
