[MSoeb]

Description: A forwarded motion has layout issues, if it is opened via the link in the original motion. The page is broken and need to be reloaded to see and use all buttons. This problem also occurs, if the user opens the original motion link in the forwared motion. In both directions the content of the motion is not fully loaded and broken.

original motion with a forward link:

situation after click on forward link:

page reload -> whole content appears

view after click on original motion link: for example: the livestream can't be closed. page is broken and needs reload.

Reproduction:
pre-condition: two meetings with forwarding options needed.

1. open meeting A
2. open motions
3. create a motion
4. forward the motion to meeting B
5. click now on the forward link in the original motion
6. -> now in meeting B the layout is broken -> reload page
7. navigate back to the original motion by clicking on the link of the original motion
8. -> layout once again broken

What should happen:
By opening the links to switch back and forth, the layout should work without reload.
