MV3 (Beta @ 462fa9a) tab close on cache-miss DNSLink website load

[lidel]

When I open a new DNSLink website, ~50% of time the tab gets closed instead of showing the website loaded from my local gateway.

Prerequisites

1. have local IPFS node running (e.g. ipfs desktop)
2. Install MV3 (Beta @ 462fa9a) in Chromium-based browser

To Reproduce

1. Create new tab
2. Paste domain name of DNSLink website (like docs.ipfs.tech, cid.ipfs.tech etc) in the address bar and hit enter
   • This should be a new domain name, that you did not load before (cache miss scenario).
3. Sometimes it works fine, sometimes (~50% of time?) the tab will get closed. When I repeat the steps for the same domain in a new tab, its the same (~50% of time?)

I can reproduce this reliably in both Brave and in Opera.

This no longer happens with the refactor work that went in a few recent PRs, please reopen this if this is still an issue.
