When configuring a new layer in GeoServer, with default tile caching, or when adding tile caching to a
a layer, the grid subset bonds for it as set to “dynamic”, as in, computed on the fly from the layer
own bounds (which can change over time):

Seems like a reasonable thing to do. GeoServerTileLayer can compute the bounds dynamically, while the configuration object backing it,
GeoServerTileLayerInfo, containing the XMLGridSubsets objects, has them with null bounds.

However, things can become less dynamic… let’s make a GetCapabilities run, the “dynamic” bounds will be computed so that they can be reported,
and then go back to the layer tile caching tab, you get this:

If the layer is not saved, and the configuration reloaded, the page goes back to dynamic bounds. But save the page, even for unrelated changes, and the
bounds are now carved in stone, and I know no way to make them go back to dynamic.

This seems wrong to me. The issue is happening in this line, updating the xml gridset bounds while computing the tile layer dynamic bounds:
