The problem here, is that the context module is not the same width as the gallery, so aligning to left will align it to the left of the context module. As you can see, this looks a bit odd ...
The logical reason to why context module width is more narrow, is because text is more readable when the lines break at reasonable widths (like a book).
And then, since your gallery has it's own width (it's not set to "wide" 100%), it's difficult to align the breadcrumbs exactly with the gallery. We could align it to the screen with CSS, but this looks even more strange:
As a last resort, you could either set your gallery to WIDE and then we can align the breadcrumbs with the stage. Or you could set the same width for gallery module as context module, so that we can align breadcrumbs left with the gallery left. This may cause some issues, and would require you to have same width/layouts for all pages ... It would look something like this (position was adjusted manually to simulate what it would look like):
Not bad, but not a world of difference, and I'm not sure it's worth the compromises (requirements) to synch.
Wouldn't it in this case be just as good to align left the entire context section? Seems more balanced, and certainly is less complicated:
