Widget for multivalued file field overlap

@christosgeorgiadis Thanks for the merge request. However, I think you have not implemented the original patch correctly. The 'table' itself has the class '.table-file-multiple-widget' and its child td should be set to 'height: auto'.
Your solution works, but only because the table in question is a child of another table. I can imagine that there may be situations in which this is not the case.

I don't know much scss so I can't proceed any further to address your requirements. Someone more experienced should make a commit to the MR so that the patch is implemented properly.

Waiting for an RTBC here. Thanks!

I've tested the MR and while it does fix what it was trying to, I feel like we should address that the Alternative Text textbox, description and remove button can overflow outside if the browser window gets too small. Or should this be another issue of its own?
