Openable not correct for some window models

window/103236, window/102905 and window/102803 also have an additional issue where the typically fixed top half of the window is also moving? I chose the first moving part as the actual window but the second moving part needs to be fixed imo.

window/102896, window/103032, window/102906, window/103070 and window/103052 also have the same issue but horizontally (so IRL this would make sense - some doors also have this issue) but it's problematic bc if you pull both doors to the opposite side, the window is technically closed but we'll measure it as open since both joints are fully extended

set joint limit to half

[ChengshuLi]

choose one of the two limits that are closer to 0 as "closed" and the other as "open"

some objects are by default open (carton, briefcase, etc)
