These fixtures were written while porting to Avalonia, as an author's own
verification step rather than as coverage: reflection asserting that a type
derives from its base and that a property has the type it is declared with;
literals (MinHeight 29, Padding 3, MaxWidth 900) copied out of the .axaml
beside them; a property override asserted only so pane descendants stay
reachable from tests. None of them can fail except when someone deliberately
edits the line they mirror, and then they fail as a chore.
StartupPerfTests keeps its two [Explicit] benchmarks, which print per-phase
timings worth reading. The third was a wall-clock assertion (8 CoreLib copies
must settle in under 15s) that ran in CI, where a shared runner decides the
verdict; as [Explicit] it would be strictly dominated by the 200-assembly
benchmark it was derived from, so it goes.
Two fixtures are trimmed rather than deleted, because their kernel is real:
XmlDocLoader's ref-pack fallback has no other test in the repo, and the
MenuIcon metadata rasterisation was dropped once during the port already.
Both now assert that without booting MainWindow to reach it.
This is worth about two seconds - it buys reviewers less to read, not CI
less to do.
