When that happens, each view will add its own copy of the list of items to be added to the contextmenu, resulting in duplicate entries.<br />
<br />
This patch prevents the consequence of calling `populateContextMenu()` multiple times by checking if the target view is indeed the one currently active in the mainWindow that it belongs to, *after* removing the items from `d->addedContextMenu` from the target `menu`.<br />
<br />
Preventing the multiple calls might also be possible but would probably introduce more complexity (connecting and disconnecting `populateContextMenu()` in reaction to `focusIn` and `focusOut` signals?)</span><span style="padding: 0 2px; color: #333333; background: rgba(151, 234, 151, .6);">and intends to remove the menu items added in a previous invocation before adding an updated list of actions</span>.<br />
