Expected Behavior

Once the context menu (overflow button in a post card) is shown, it stays where it was rendered until it's dismissed.

Actual Behavior

Depending on where the context menu is rendered, it changes position when interacted with.

Steps to reproduce

1. Navigate to the Following tab
2. Tap on the ellipsis button
3. Notice that the context menu is not showing everything.
4. Scroll the content inside the context menu
5. ⚠️ Notice that the menu changes its size and position

Note

This doesn't happen always, it appears to happen mostly when the menu is rendered to close to the top or bottom edges of the screen.
