Maybe related to #8255 and #7706
@evanpickett You worked on this recently, do you mind taking a look at this issue?

[evanpickett]

I'll take a look tomorrow and see if I can work on it

[evanpickett]

I'm finishing up my semester at university and then I'll have more time to look at this, sorry for the delay!

@ilippert I am having trouble reproducing this on my mac, I can click wherever I want but it does nothing
@mlep You recently had the similar issue.

Do you use the "Custom preview layout"? (e..g a modified version from JabRef's default)
Do you display the DOI as hyperlink?

[Siedlerchr]

Found the bug. Simple fix is on the way

sorry for no response for days - pandemic everywhere... thanks for the fix, and for looking into it!
