Alignment zone filter shifts italic glyph cell

I found this very weird bug, when adding filters to the alignment zones in the font info, the glyph cell in italic is shifted

Here a screencast:

Please don’t add filters to the default metrics.
The x-height is used to compute the slanting. And if you remove it, it falls back to the next metrics and that has an influence on the slanting. So that is not a bug.

Georg is it OK to duplicate the default metrics – this way I can get them to show up across the whole font and not just on those glyphs that Glyphs says the metrics is to show on. Seems to be OK so far.

This is also what I‘d want. Didn‘t expect any problems with adding filters to the default metrics tbh.

I still think it‘s a bad idea to have vmetrics and zones combined 🤷
