Streetlabels mixes the offset done by Polyline Offset

[dave-driesmans]

Describe the bug
We have a map where we want to display direction flows in the street. We use Polyline offset for that and that works fine.
As soon as we add the streetLabels Renderer it mixes the offset. Negative becomes positive for some.

Left with StreetLabels, right without

Can anyone point me to a possible solution? Or where i should look in the code?

Ok, it's due to this

if (this._getBearing(startCoords, stopCoords) < 0) {
       layer = this._getLineStringReverse(layer);
}

When i leave it the lines aren't swapped. The text is up side down for some polylines but that's ok for the moment.
