Description Brock McNuggets 2014-03-25 04:39:15 UTC 
To replicate
1) Open two Dolphin windows
2) Select the Window Menu > More Actions > Full Screen
3) Select the Window Meny of the "Information - KDialog" warning. Use Attach as tab to > [other Dolphin window]

Now when you click the dolphin tab you cannot resize it, and clicking on the background full screen window brings you back to the warning but does not take you to the full screen windows (it is waiting for the warning to go away).

Close the Warning tab will correct things.

Expectations: Why have the option to tab that warning screen at all?

Reproducible: Always

- are the tow dolphin windows one process? ("new window" rather than starting another dolphin)
- what '"Information - KDialog" warning' - how to trigger it?
- which dolphin window  does that dialog belong to? fullscreen or not fullscreen?

Saw the video - it's the Alt+F3 warning ~/.kde/share/config/kwin_dialogsrc (it's not really important, though)

This is not a bug at all.

The dialog is modal for the fullscreened window, ie. blocks all input to it while present.
Whether it's tabbed somewhere or not does absolutely not matter.
The behavior won't change by tabbing it somewhere and any attempt to activate the blocked window will simply activate the modal transient instead (you're forced to deal with it first, that's the idea of it)

In general, you're allowed to tab windows together as you like it - whether it ultimately makes sense or not is up to you.

ftr:
dolphin, particular modal dialog or fullscreen state are all irrelevant for this case, it would boil down to "modal dialogs should not be tabbable at all"
