Additional context

On the newest version of Chrome as of now (Version 149.0.7827.54 (Official Build) (64-bit)), when you open a PDF using this extension, AND add that PDF to a tab group, reload Chrome, you'll see that the PDF tab is gone and it is turned into a default "New Tab" page, but if you press backwards button, it'll reload your PDF, but nonetheless, it is really annoying. I tried this on Chrome version 148, and this issue didn't happen. I really hope you fix it. Thanks.

PDFs opened through the extension in closed tab groups also appear to be affected. Unfortunately, this results in the loss of the tab as history isn't retained for tabs in closed groups. Restoring the group results in a "new tab" without the ability to navigate "back" to the PDF.

But I tested right now, and I can still navigate back to the PDF just with a single backwards click. On the latest version of Chrome.

Did you close the tab group (via right click on group -> close group) before relaunching Chrome, or just collapse it?

Tab group open + Chrome relaunch -> Tab reverts to "new tab", but PDF restored by navigating "back"
Tab group closed + Tab group reopened (in the same browsing session) -> PDF opens in tab as expected
Tab group closed + Chrome relaunch + Tab group reopened -> Tab reverts to "new tab", and PDF cannot be restored

It's also interesting that the tab appears to be lost not when reopening the closed tab group, but immediately upon relaunch. Examining the tabs in the closed group before relaunch shows "PDF.js viewer" as the title. However, the title "new tab" can be seen in the closed group following a relaunch (before actually reopening the group).

Oh you're right, no I collapsed it.
IDK if it's a Chrome bug/behavior or it's because of PDF.js, it's really annoying.
