In the documentation of the layers in the manual the layer pre main is missing. This has been shown latest in https://tex.stackexchange.com/q/506317/95441. I am pretty sure that I have seen this eariler, too.
fixed in https://sourceforge.net/p/pgfplots/code/ci/2581cafe7f2504fa7191f9e8b0d55cf84919217c/
