Empty column 1 collapses, column 2 gets shifty

[ericscheid]

This only happens with the v3 renderer, not the legacy renderer (using legacy column breakers).

# Column calumny

\column

## column two??

This doesn't fix the actual issue, but a quick workaround is:

# Column Calamity
:

\column

Here is some text in the second column.

Observation 1: a block with zero height doesn't trigger a column break. legacy renderer/syntax inserts a <pre><code></code></pre> elements, which take almost 12px:

If I set height of .columnSplit (which is zero by default) to at least 1px, it starts to work, but in an unexpected way:

If I further disable break-before it works as expected:

I've tried to read about break-after and break-before properties, but still have no idea why it behaves this way

break-before was added by @calculuschild in #1184

I think this is resolved at some point-- the property is now break-after rather than -before. And I can't reproduce this. Possibly it was the columnWrapper that did it? I don't see it in the DOM in the screenshot above.

I'm going to close this-- please reopen if i'm mistaken.
