[PresentWindows] Make it more Latte friendly

[Ryū Ketsueki]

So far this is one of the best to present windows or show desktop grid. It's nice to have on a Panel but not at all when using on Latte Dock with a custom icon. The icon does not have the same size as the rest of the icons on the dock, neither it zooms on hover like the others, doing leaps on size instead of being an actual zoom. It happens with most of the icon packs I tested. I'm using McMojave here and assigned the plasmoid to use deepin-multitasking-view as icon. And there are still times it does not zoom at all, staying on the same size. This is not an issue with Latte itself but with the plasmoid.
