Has anyone else come across a situation where sp page builder applies a z-index of an overlay of 1, even when no overlay is specified in sp page builder?
I've tested with page builder 3.8.8 and also 4.0.3 and it appears to be the case in both versions.
I've worked around the bug by applying the following custom CSS:
.sppb-row-overlay {
z-index: 0;
}
