The behaviour of liked comments has changed and I am not sure if it's intentional. But I am finding it tiring.
When I like a comment, it shows that I have liked it with a heart like this:
But if I refresh the page, that disappears and I cannot tell if I have liked the comment or not, just that someone has liked it:
Unless I mouseover that comment:
But even then, the heart symbol isn't displayed. I can only tell that I have liked it because the liked button turns black and says 'LIKED' in past tense instead of 'LIKE'.
So what is happening is I keep moving to like something, that I have already liked. But I can't tell that I have liked it, till I move the mouse towards that button.
I am aware you are making some changes to the the site, so wasn't sure if it was a glitch that has occurred because of that. Or whether it was changed by design.
