"Select all" checkbox heading doesn't render sometimes

[dpanov]

Summary

Sometimes the "Select all" checkbox heading doesn't render. When that happens, it shifts the rest of the table headings to be misaligned with the table columns.

Expected behavior

The "Select all" checkbox should always render (unless selectable={false}).

Actual behavior

Sometimes, the "Select all" checkbox doesn't render.

Steps to reproduce

This happens very rarely and usually fixes itself after a page refresh. I haven't found a way to consistently reproduce it.
