Pin message confirmation options gets off screen/outside the window if the link+embbed is long vertically (like a x/Instagram/tiktok/YouTube shorts aspect ratio video)

[fluxbug-flutter]

Steps to reproduce

1. Send a video link on chat that creates a long embbed
2. Try to pin it

Expected behaviour

Since the embbed is too big, it should be cut or vanish in the bottom respecting the limits of the pop.up window size, enabling the buttons to be visible

Actual behaviour

The pop up window gets so long that there is no space anymore at the bottom, pushing the buttons completely out of the window and making them even go out of the display area
