Priyansh Garg abe876a4a4 compose: Fix auto-resize issue on uploading files in preview mode.
On uploading a few files from markdown_preview mode of compose box and
then switching back to edit mode, the compose box doesn't get resized.
It even doesn't allow to scroll through the content.

Fixed this by switching back to the edit mode everytime user uploads
some file in markdown_preview mode as there's no use of staying in
markdown_preview mode anyways after uploading a file as the preview
doesn't get updated.

Also, updated the corresponding test cases.

Fixes: #16296.
