Wrapped text becomes a single line when the expected item rectangle is not in the viewport

[YukinoHayakawa]

I'm making a resource manager displaying item groups consist of a thumbnail and a name respectively, and I'm wrapping the name text like the Windows Explorer does because I don't want it to expand the width of the group. However this strange behavior happens when I moves the manager window around, and disturbs the layout.

I've found that if TextWrapPos == -1.f is used to determine whether wrapping is enabled, but I can't see any difference changing it, so I suspect there might be some other positional / clipping calculations involed.

I hope this could be fixed or an corrected code replacing the old in the demo. Thank you.
