Very, very odd...
I thought, before answering you, I test it again. GitHub link copied, inserted: Worked! Huh?
Shut down MorpOS, boot again, launch Wayfarer, copy link again: Does not work!
I just cannot see what is written in the second (between 'Update README.md' and 'b58d4d5') and third column (under '75 commits'). There are only grey bars. Unfortunately I cannot add a screenshot...
I could send a mail if it helps.
