Wood will expand and contract across the grain, and a wide panel made of solid wood could change width by a half of an inch, warping the door frame. By allowing the wood panel to float, it can expand and contract without damaging the door. A typical panel would be cut to allow 1/4" (5 mm) between itself and the bottom of the groove in the frame.

[1] They are typically constructed of two or more panels joined together by crossbeam braces which can separate due to age and material instability caused by fluctuations in relative humidity ...
A scarf joint may also be used to fix problems caused when a board is cut too short for the application. The board can be cut in half with a tapered cut yielding a scarf joint. When the joint is glued together, the tapers are slid against each other so that the two sections are no longer in line with each other.
Smooth sheets of paper were pasted over the painted surface of the panel, and a layer of muslin over that. The panel was then fixed, face down, to a table, and the wood planed away from the back until it was "as thin as a plane may safely go", and the remainder scraped off with a sharp instrument such as a razor.
