Vector Tile Layers do not clip to layout map frame when mask enabled

[baswein]

What is the bug or the crash?

When a mask is enabled on a vector layer Vector Tile layers (tried ArcGIS and Maptiler layers) do not clip correctly to the map frame edge when exporting as a png, pdf, or svg.
It does not seem to matter if I have Always Export as Vectors enabled or disabled. This is the work around described in #49638 and #48624. This might be the same issue but it seemed different enough to make a new issue and let you decide. Thanks

Steps to reproduce the issue

1. Add a vector tile layer
2. Add a vector layer and turn on labels and enable masks
3. Make a layout and add a map with space on the edge of the page.
4. Export as a png
5. Observe that the tiles are not clipped to the map frame boarder

Some output examples with the page color set to orange and the map frame as a thick black line:
Without Mask (expected output):

With Mask:

Thank you for reporting this issue, but I really do think this is the same as #49638 and #48624

If you know someone willing to fund this, we can try to contact someone close to the Qt project to fix it in Qt. If so, please contact me at julien dot cabieces at oslandia dot com
