Comment:

 @rabmalin I am able to reproduce the issue as you describe. I would not
 expect `$content_width` to affect the size of `the_post_thumbnail( 'large'
 )` when generated on the front end, so I would consider this to be a bug.
 From what I can tell, `image_constrain_size_for_editor()` has not
 respected the context for 'large' image sizes for at least 8 years, so I'm
 not sure what back-compatibility issues might exist, but it's worth giving
 this a look for 4.5.
