#13158 (as of commit 3e456bb) experienced a build failure on the "Test - Keyman (Web)" build. Upon inspection, it's because the changes made therein... caused the collation folder for coverage reports to become empty! In essence, our coverage-reporting setup is and has been pretty much broken for a while. That said, the 17.0 version of the report is fine - the coverage action was written before the big reorganization of Web-related code we did earlier during 18.0's alpha cycle.

Here's a link to the coverage report from #13158's parent PR: https://build.palaso.org/repository/download/Keymanweb_TestPullRequests/522532:id/build/coverage/index.html. Note how only predictive-text stuff appears within it! The same can be seen for builds against master (and now, beta).
