Message:

Fix #23257: MVTTileTest has an infrequently hit race condition (patch by marcello, modified)

The race condition is dependent upon calculation speed; if the layers get loaded
prior to the image loading, it is possible for us to get to the point where
we expect the image to be loaded, but it isn't yet.

Modifications are as follows:

  • Reinitialize tileSource and loader before each test, but initialize the cache once and clear that between tests.
