How do you unhide an undocked toolbar tab?

While editing a blueprint, I undocked my toolbar on accident.(how easy it is to do that is annoying as crap by btw)
Annoyed at the disruption to my work, I was flustered and unthinkingly hid the toolbar tab while it was undocked.
Now I have a floating toolbar that I can’t move, and can’t unhide the tab.

Ive tried resetting the layout, but that didn’t work.

How do you unhide an undocked toolbar tab?

Click window and hit tool bar to make it come back.

I have no idea how you managed to hide the tab while it was undocked. I can’t even do it. Its grayed out.

I’m using 4.18.2. I do have a project that use 4.17.2. Let me check if it happens on there.

Yea, I can confirm that undocking and hiding the toolbar happens in 4.17.2. Now I can’t find a way to redock it. This would make me slightly upset if this was the engine I used. I guess update to 4.18 if you can. Or just resize it to the top.

Its not gone.
Its floating with no tab.

The toolbar option in Window is already checked.

What version of the editor are you using?
Im using 4.17.2 , and Hide Tab is not grayed out for me when I undock windows.

Solution found:

Dragging a different undocked window into the broken undocked window allows you to unhide the broken window’s tab.
