CustomGeometrySourceOptions.withClip always enabled?

[Helium314]

Using a CustomGeometrySource appears to display only geometry for one tile, and does not allow geometry from neighboring tiles to across a tile border. For example the the blue and red lines on the screenshot bekow come from a CustomGeometrySource:

There are 4 tiles in the image, I think it's visible where the tile edges are. You will notice that the blue road in the center has a white section in the bottom left tile. This is because the road is not returned when the source queries features for this tile.

Reading in documentation, I understand it should be possible to get data from outside tile boundaries using withClip.
I would expect that it allows the blue lines to cross tile boundaries, so they are displayed completely. But actually it seems that the withClip value does not change anything, it always looks like in the screenshot.

Is this a bug, or am I misunderstanding what withClip is doing?

In short, the expectation of the issue reporter is that withClip = false would result in that the line marked in orange from the tile marked in green on the below picture would cross into and through the other tiles, as the line has not been clipped.
(And since the line is likely part of the upper left tile too, would be drawn two times - one time as part of the geometry contained in the upper left tile, the other time as part of the geometry in the lower right tile)
