The PDF preview on the Files tab and the document preview of a Collab note
were about 150 px tall: the object carried flex-1, and in a column without a
fixed height that falls back to the object's own height instead of 74vh.
A tooltip no longer opens when a closing dialog hands the focus back to the
button that opened it. It floated over whatever came next, at the place the
button had before the page moved. Keyboard focus still opens it.
The table view sorts its dates with localeCompare, and two NaN fallbacks and
an unused import go.
