the browser icon is updated on all windows instead of only the window with the active tab

Reproduce:

• open two tabs at different URLs in two different windows
• mark one tab to re-open periodically
• move to another non-bookmarked tab in the same window
• move back to the bookmared tab, the browser icon displays the periodicity on all windows
