Gallery format title is not fully clickable

Assigning either Gallery or Image to a sticky post ends up making the title not fully clickable.

I have a post titled “Photos” and if I select Gallery format for it, then on the front page the word Photos is not fully clickable. Only the “os” end of the word can be clicked on to go to the post.

This post is marked Public with Sticky visibility.

If I use some other format – Standard – the whole word is clickable. If I make it un-sticky, then Gallery too works fine and whole title can be clicked.
So presumably the combination of sticky posts and Gallery or Image formats have a problem in that the title is not fully clickable…

I’ve looked at the CSS in the debugger, nothing jumps out. Any clues on what I can try to fix this? This is for an internal site, so don’t have an URL to post as example…
