getFullWindowReservedArea() is always zero in onWindowCreatedTiling

[jmoggr]

The following will print a zero vector when call anywhere in onWindowCreatedTiling:

Debug::log(CRIT, "reserved topLeft {}", pWindow->getFullWindowReservedArea().topLeft);

The reserved area is zero until the first call to recalculateWindow for the new window, when it will have the expected (non-zero) reserved area.

I would expect updateWindowDecos() to update the reserved area, however it does not do that on the first render because CDecorationPositioner::onWindowUpdate returns early here.

I'm raising this because I'm not sure if it's a bug.

It's not intuitive, but it appears to be a non-issue in practice. I only came across this as a red-herring while debugging some of my own spaghetti: I broke recalculateWindow so the reserved areas were wrong.

I don't think it can be as everything is being calculated at that point
