Cover group buttons disabled by single member of group

[fishter]

Conditions:

1. A cover group containing at least one cover which does not give any feedback on position.
2. When the cover(s) in the group which do report position are at fully open (or closed) Result: The open (or close) button on the group is disabled, removing the possibility to use the group control to open (or close) the non-reporting shutter.

If a cover does not report position then the buttons controlling that shutter should not be disabled, as the system cannot know the position of the shutter. The cover group shown here (top card) shows the close button disabled. The individual covers are shown in the bottom card; here we see that the second cover can be controlled.

Describe the behavior you expected

If a cover group member is not reporting its position, it is wrong to assume it is in a particular position and then disable control buttons. If any member of a cover group does not report position then the UI should leave the open/close buttons enabled at all times.

Steps to reproduce the issue

1. Create a cover group with at least two members. One cover reports position, the other does not.
2. Close the reporting cover.
3. You cannot now close the non-reporting cover using the group commands.
