Unable to manipulate added views on an image slide after phone lock/unlock

[mzorz]

When adding views in the composer view, then locking the phone and unlocking, you can't tap on the added views any longer. You can still add more views and these can be handled, but not those that were added before.

Steps to reproduce:

1. run the app
2. add a piece of text
3. confirm you can tap on it, drag it around, resize, etc
4. lock the phone
5. unlock it
6. verify the app is running and it shows the added view, but you can't tap on it, resize it, nor move it. You can only manipulate the background picture.

It will work when you tap on the FrameSelector to-reselect.
