Bug Summary

Floorp can't restore tabs on startup after closing tabs the other way (like a multi-selection ctrl-w) with a mistaken warning dialogue instead of quitting normally.

Reproduction Steps

1. Open multiple tabs
2. Enable session restore ("Open previous windows and tabs") over Settings
3. Press the close button
4. Warning dialogue similar to multi-tab ctrl-w
5. Re-launch the browser

Expected Behavior

Closes usually without that confirmation and restores back when opened

Actual Behavior

Shows a dialogue similar to closing multiple tabs at once, and they can't be restores on the next startup

Screenshots

Browser Version

11.17.4 (64-bit)

Operating System

Windows 11

Additional Context

I was testing it briefly on Windows, can't recall this happening on Linux (Flatpak) last week.

Well, since switching profiles back and forth fixed it, I guess you can't really reproduce, sorry...
