Bug 486651

SUMMARY
As the title says. Otherwise, if the panel is configured to 'Auto hide', Yakuake can correctly fill the space.
I'm not sure if this is a Yakuake issue or a Plasma issue that is not correctly advertising the behavior of the panels; let me know if you want me to bring this issue somewhere else.

STEPS TO REPRODUCE
1. Configure a Plasma panel to 'Dodge windows'; it doesn't matter the placement of the panel; the issue is reproducible always
2. Configure Yakuake to fully expand on both width and height
3. Open the Yakuake window

OBSERVED RESULT
Yakuake will stop expanding when it finds a plasma panel, leaving an empty strip along the edge of the screen.

EXPECTED RESULT
The Plasma panel will retract (hide) to dodge Yakuake's unfolding window, allowing it to cover the designated screen space.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
(available in About System)

ADDITIONAL INFORMATION

Thanks!!
