Text provided by keyword label is not searchable when using multilayer = 3d

[DiegoBneiNoah]

Suggestion:

I have no idea what the cause is and also what the solution would be but I ask that when using multilayer = 3d I the text provided by the "label" option can be searchable. Because only when drawing using multilayer = 3d I can't make the vertex label searchable.
From the section "B.1.4 Simple example" extracted from the tikz-network manual according to the code below, the search works normally:
