Is our Vertical Metrics spec inconsistent? #2841

Open davelab6 opened 4 years ago

davelab6 commented 4 years ago

Observed behaviour

A user writes that the vertical metrics of fonts updated within the last few years that I believe use our latest VM spec are rendering inconsistently:

I'm creating my own website and wanted to use Montserrat for the navigation bar because of how great it works as an overall heading style. I've noticed that browsers based on Chromium display everything properly, but other browser types (Firefox, IE11, Safari) do not. I've attached a picture for reference (text alignment and padding changes). There isn't anything in my coding that specifically calls out webkit browsers, and if I simply change to another font such as Open Sans, then the issue goes away. This issue is noticeable in Montserrat, Comfortaa, and many other wider Google Fonts.

Expected behaviour

Can we reproduce this, and determine a vertical metrics spec that renders consistently?

I'm marking this as urgent because it is very important to confirm if our current guidance is bad...

@felipesanches please prioritize this

I will try to figure this out during this next week.

@m4rc1e or @tphinney, can any of you help me here to replicate this issue and figure out if there's something wrong with our vertical metrics guidelines?

My difficulty here is in setting up a way to replicate this. As the user do not seem to have provided sample files from his website project, then I think we may need to create small HTML+CSS files ourselves. I am not sure what would be the minimal setup to replicate this.
