Grouping two symbols and then locking one of them (Lock position in its
properties) left the group in a broken state: dragging the unlocked symbol
pulled it away while the locked one stayed, and dragging the locked one
did nothing. The move simply dropped locked items, so the rest of the
group went without them.
A group with a locked member now does not move at all, whichever member
is dragged, and the status bar says why. This is the rule the item-groups
proposal (discussion #1070) set out for this case. The same rule applies
to the arrow keys and to the Align commands, which share
DiagramContent::removeNonMovableItems().
Also fixed on the way, for a plain selection with a locked symbol: a wire
between the locked symbol and one being dragged kept its user-placed text
moving with the dragged end. Such a wire is now redrawn only, as a wire to
an unselected symbol already is.
Checked in the GUI on two symbols joined by a wire (grafcet example),
master against this branch, positions read from the saved file:
- drag the unlocked member: master moves it 190 px, this branch moves
nothing and shows the message
- arrow keys on the selected group (3 runs each): master moves the
unlocked member, this branch nothing
- the same two symbols ungrouped: both move the unlocked one, as before
- user-placed wire text: master shifts it 190 px, this branch keeps it
ctest: 34/34.

The keybord shortcut for texts group alignment change. Now it's ctrl + arrow-left/up/right
