Cannot open multiple doc pages concurrently from notifications

While working on #12193 (closed), after merging the branch for #12271 (closed), I see 3 notifications: running in a VM, I2P removal plans, 32-bit CPU. If I click two or more of the “More info” links, then only the first one works: for each of the other ones I am told that Tor Browser is already running and I should close it. I didn’t check if that’s the case if I wait longer between clicking on these links, but regardless: these notifications all appear roughly at the same time, so we are effectively encouraging users to click on them very quickly.

How hard would a technical solution be?

The code lives in config/chroot_local-includes/usr/local/bin/tails-documentation and config/chroot_local-includes/usr/local/bin/tor-browser in our main Git repo.

Low priority as very few actual users are affected currently: the I2P warning will go away in 2.12, and users should pick a 64-bit CPU for their VMs. Still, it would be good to fix this before we discover this problem again (or fail to) next time we add other such notifications.
