I have a screen, with a flexbox root container. At the top, there is a header label, and a flex repeater. Below that, there is a percentage coordinate container. When I place an element into the coordinate container, and click it to resize, it does not place the resizing box around the element, but rather somewhat above it. It's still functional, just really annoying to use.
The height of this difference seems to be determined by how tall the stuff above the coordinate container is. When I widened the page, so that the header was one line instead of two, the box got closer to the image.
The issue also exists when putting other components inside the container, eg I tried placing an embedded view component inside.
There's another more recent topic about it as well I can't find, but it mentioned being an issue I think when the coord is set to percent. Try setting to fixed while you're designing
My wife complains I squish too many too! (only mozzies though, otherwise I'm quite eco-friendly, just not to the ones whose sole purpose is to bite me)
