pub fn push_sizer(out: &mut String, copies: &str, opts: &Emit)Expand description
A CELL_SIZER around copies, which go inside a cell’s or a heading’s
CELL_IN after what it holds.
copies is the host’s: one block per distinct run, each drawn with the
classes and the element the real controls take, since an element rule an
app writes for button reaches a copy only if it is one. Nothing in it may
be a control anyone can reach: aria-hidden here and visibility: hidden
in the sheet take it out of the accessibility tree and the tab order, and a
copy carries no address. Empty writes nothing.
