Annotation doesn't disappear while the companion window is opened

[iribarnesy]

Steps to reproduce:

• On the demo app
• Create an annotation and save it. Don't close the companion window
• Then, remove this new annotation

Result:

• The drawing of the annotation is still visible (while the companion window remains opened)

Expected result:

• The drawing disappear

Additional steps:

• Use the 'New annotation' window (still opened) to add another shape, save it.

Result:

• The previous shape come back along with the new one

Expected result:

• The new shape should be alone

It seems that the companion windows are strongly linked to the annotations they draw. Moreover, the shape drawn doesn't behave in the same way as the ones saved.

Questions:

• To the extent that it is possible to avoid the above issue by being rigorous with the companion windows (always close an old window):
• Is it possible to force the close of the companion windows?
• Or can it be considered to make the annotations and the companion windows not strongly linked? For example, have just one companion window for the creation and the edition of the annotations.

Thank you in advance for your answer :)
