Auto-sizing doesn't work if children have only min_height.

Rust OS/X

What you did

In Bevy, I create a container element whose height is 'auto', and whose layout is a flex column. I then give it several children whose height is specified by min_height.

What went wrong

I would expect the container to compute its height so as to fit all the children. Instead, the container height is minimal (only padding), and the children overflow the container.

However, if I change the children to have height instead of min_height, it works correctly.
Alternatively, if I add some text nodes inside the children, it also works correctly.

I am unable to reproduce this. The following HTML snippet causes the outer div to have a height of 90px on both web and with Taffy:

<div id="test-root" style="display: flex; flex-direction: column; width: 50px;">
  <div style="min-height: 20px;"></div>
  <div style="min-height: 30px;"></div>
  <div style="min-height: 40px;"></div>
</div>

Well, I can certainly reproduce it. Did you get a chance to try the minimal example I posted?

Oh sorry, I completely missed that you'd posted a code example. I will check it out.

I briefly looking into this, and I was able to reproduce the issue using your provided bevy sample. But I was not able to reproduce the issue when translating it into a Taffy gentest. Will try to investigate this further when I get a chance.
