[BUG] Adapt window width

**Describe the bug**
We lose widget information when we add content to it. For example adding a new comment would involve losing a part of the upper section of the widget if the width is too small.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to 'Any widget and make it smaller'
2. Click on 'top right parameters of the widget'
3. Go to 'Comment and add a new one'
4. You should notice the loss

**Expected behavior**
We expect the window to remain the same.

**Screenshots**
