Using custom scopes in advanced mode query params

[artsiompeshko]

Currently, custom scopes are only supported for simple query params mode, trying to use advanced group params and custom scopes as its key does not work.

E.g.
Simple mode params work as expected:

q[custom_scope_name]: value

Advanced mode params do not work:

q[g][0][m]: and
q[g][0][c][1719018103783][a][0][name]: custom_scope_name
q[g][0][c][1719018103783][v][0][value]: test
