Experimental tests (or any subfolder) are not run in github actions

[xPaw]

While I was looking at the floating point stuff, there are some tests that cover it, but they're in experimental folder, and test runner doesn't run tests recursively:

php-memcached/.github/workflows/build-and-test.yml

Line 84 in d3b8ce1

php run-tests.php --show-diff -d extension=modules/memcached.so ./tests/*.phpt

Is this intentional?

This may have been an oversight in the migration to GitHub actions. Would be glad to see a PR to run these additional tests.
