dompdf display: inline-block; with margin are rendered different than browser

The code below renders different than in a browser. It looks like the top margin is not applied when 2 blocks are rendered. I quickly looked and could not find a duplicate in the issue database.

There appear to be two issues. First is the vertical alignment of the blocks. That should be addressed once the vertical-align branch is finalized. The second issue is that the border around the second block is cut off. I'll need to look into that issue a bit more.

Thanks for the analysis ! During development of a project I ran into issues. Somethings it is hard for me to figure out if my problem is a duplicate or not. Would you consider it helpful is I report these issues with the probability it is a duplicate ?

It's still helpful, yes. Sometimes I can find the original issue and link to it. And that way when I release a fix for the issue I can test any samples provided in your issue as well.

And sometimes I can't find the original issue even though I know one exists so I don't mind the duplicates if you can't find an original report. Though, obviously, if you find a relevant issue and have nothing new it's easier to track if you just add a comment to the original.
