[(Graphical) Bug] Pasting many attachments into the message box makes it do a weird out of bounds thing

[sabogalc]

The only way to send attachments in MyMessage is to either drag and drop them or copy and paste them. There is currently no file selector/attach option. Below is a video of me showcasing this bug in dark mode and in light mode (it's more apparent/intrusive in dark mode).

iOS handles situations like these one of two ways, depending on how the attachments are added to the message box. The first way is by making the message box the same vertical length as the attachment when it is pasted in (like with MyMessage)

Vertical.Pasted.Attachments.mp4

The second way is by making the attachment preview a horizontal menu when the attachments are chosen from the photo selector instead of pasted in.

Horizontal.Attached.Attachments.mp4

WebMessage has a similar set up to the photo selector, but it does not allow for attachments to be pasted in the middle of a message, which I think it should for situations like this one. Also, WebMessage does not have file previews for queued attachments either.

I think for the time being, MyMessage should have some message box height limit for situations where there are many attachments pasted in, and once a file selector is added, the menu should be horizontal like it is on iOS, or a grid/table like it is in WebMessage (but with previews). Let me know what you think of this issue.

Update - My version of macOS (Mojave) does a similar message box height limit thing, and attachments can only be dragged and dropped in. I'm not sure if later versions of macOS/Messages have an attach button.
