Pano downloads files from copied URLs and freezes the UI for a while after the download about gnome-shell-pano HOT 3 OPEN

This gets stuck in src/utils/linkParser.ts, in the p.write(data) line, about line 107. It attempts to parse the file you give it as html, which is very slow for a 1GB file.
This is imperfectly but trivially fixed by only p.writing the first 10000 or so characters of the file, this is always instant, and I cannot find websites that don't have their meta tags in the first 10000 characters.

Would it be possible to merge request?

@ttmx I guess you could do a merge request, yeah. Maybe even a fork - this extension does not seem to be supported anymore. I'd love to use your changes, though I don't really have much time to tinker with it and debug the extension.

Maybe a better solution would be to use a separated single thread that will return the extension's preview contents once it's loaded? This won't fix the full file download issue, but it would improve the overall experience.

I just faced the same issue. I was very confused when out of nowhere my network usage spiked and then my whole OS froze.
It would be nice to see this fixed, maybe by querying the type of response first and only accepting HTML, images and the like and of course having a size limit so you don't try and download a 1GB file for a preview.
It would be interesting to know how for example Discord handles link previews since they don't have this issue (see below, first link is a file that gets downloaded by the extension, but Discord is smart enough not to do that and only show the preview for the second link which responds with HTTPS/has a preview image in the metadata):

For now I guess I'll keep the link preview disabled which sucks because it's a cool feature!
