Large project images break the project modal on small screens.

[gthoma17]

Is your feature request related to a problem? Please describe.
When i open a project modal on my 13' Macbook screen, if the image is large enough it pushes the content (project text and carousel buttons) off the screen with no ability to scroll to it.

Describe the solution you'd like
I'd like to be able to scroll the entire project modal, not just the text content.

Describe alternatives you've considered
I'm adding custom CSS to my site to implement this, but it would be better if the theme did it automatically.

Additional context
Observe what happens in when I click to the third photo in the the photography project from the example site in this .mov:
