the mobile popover (like all Kendo UI popups) should close when orientation changes or scrolling occurs. In general, it would be great if the popups could re-position themselves in these cases, but in practice this implementation is quite complex and we haven't done that yet. For some reason, the orientation change does not always close the popover, though.
The simplest workaround I can come up with is the following:
popover = $(
This reliably closes the popover when the orientation changes, at least in my tests.
