Different number of subtests at top and bottom of results table

[foolip]

Looking at https://wpt.fyi/results/compat?run_id=5095555055484928&run_id=5174632751824896&run_id=5155156954185728&run_id=5128162447196160 I see "Showing 31 tests (98 subtests)" at the top of the table, but the Subtest Total at the bottom has numbers like 109 / 119, suggesting 119 subtests.

I would expect these numbers to match. (And when using view=test I'd expect the test counts to match instead.)
