Well, that's interesting. So, it worked when you entered it but, as you can see, in the post immediately above the one you entered, everything between angle brackets is missing. For example, the 3rd line of the post says:
There are indeed many other places where this comes up, the most common ones in my experience being and . The Romans spelled these words both ways.
but when I click on edit, I can see that it says:
There are indeed many other places where this comes up, the most common ones in my experience being <expire> and <expect>. The Romans spelled these words both ways.
A few lines below that it says:
We don't have either or in English, but has been attested in the past.
but in edit view it says:
We don't have either <exstant> or <exstinct> in English, but <exstant> has been attested in the past.
and that continues through the rest of the article.
Do you have any thoughts about what might cause it to be different when you enter it and when I do? I've tried it in both Safari and Firefox -- could it be browser-based? Are you using Chrome, and could that make a difference?
Thanks,
Matt
