experimental_merged_skyframe_analysis_execution breaks bazel coverage

[Ryang20718]

Description of the bug:

tools/bazel coverage //...--cache_test_results=no

with the following bazelrc should lead to a coverage.dat file getting generated under bazel-out/_coverage/

coverage --combined_report=lcov --instrument_test_targets --instrumentation_filter="//"
coverage --test_env="LCOV_MERGER=/bin/true"

adding common --experimental_merged_skyframe_analysis_execution to our bazel rc leads to this coverage.dat failing to get generated.

I've also tried, but same issue

build --experimental_merged_skyframe_analysis_execution

Could you test with 7.2.1rc2? There have been a number of fixes related to Skyframe since 6.5.0.
