Frame under a Footer has no handles and can't be moved/deleted

Is this a feature by design - or a bug?

A frame, created on a page can be dragged into the footer area.
Text in the frame can then be created or edited.
If no part of the frame remains above the footer area handles don’t appear, so frame can’t be moved or deleted.

Only work around seems to be to adjust the footer or type into the frame so its top pops above the footer.

This would appear to be bug fdo#61893. I can select the frames in the DOC provided in the example file in that bug under GNU/Linux running TDF/LO v4.1.0.4 however it is not easy and manipulation is limited. There does seem to be a problem with how LO treats frames under DOC in general and this is one of those.
