Dependencies not updating with package update

Nobody has claimed this yet.

For my wrap package, `kraken-engine`, I have sdl2 dependencies and a few other necessary ones. Whenever I put out a new version of my lib and install it with `meson wrap update ...`, all the old sdl2 packages stay and, because they're "from" the last version, re-configuring becomes a hiccup. The current solution is to just delete the entire `/subprojects` content first then reinstall my lib. Is there a better way to go about this that I didn't see in the docs, or is it just an unfortunate side-effect of a dependency with dependencies?

Start by examining the `meson wrap update ...` behavior described for the `kraken-engine` wrap and the contents of `/subprojects`; consult the relevant wrap documentation first. Done means establishing whether old `sdl2` dependencies should be removed during an update and documenting the supported update workflow or confirming the behavior as expected.
