Click & drag URL list?

[TheOverpassArsonist]

I could be wrong but I swear I remember being able to click and drag a list of URLs, for instance

about:addons
www.google.com
www.youtube.com
www.bing.com

into sideberry to have them open. I can still select and drag a list of tabs out of sideberry and have them be saved as a plaintext list of URLs, but when I drag them in to sideberry it seems to try to concatenate them together and search the string. (even if I only drag in one URL?)

Is this a setting that I enabled before and forgot about, is this a bug and this isn't how it should be behaving, or is there some completely different process that I've only half-remembered how to do?

For what it's worth, I noticed a similar issue happens with bookmarks. I thought that I may have misremembered dragging a list of URLs into a bookmarks folder then oppening the new tabs from that folder, but when I tried it even though the bookmarks panel would respond to me hovering and dragging stuff into it (opening the panel, opening subfolders, highlighting what I was hovering over, etc.) when I let go nothing would happen.

If it matters I am currently testing on Floorp (up to date) with Windows 11.

PS : I'm sorry if this is actually an issue that's open, but unfortunately no matter what search terms I tried whenever I searched through issues for it I always got a ton of results. Nothing I tried could narrow the search results down enough to be meaningful, and from some quick skimming I didn't see anything that looked like what I'm talking about.
