I was debugging test failures in #26447 and found that if I ran
test-runtime.jsdirectly it would work, but if I rantest-shadow-embed.jswith it, it would always fail :(Turns out in some of our tests, we manually set the streaming supported flag through
setShadowDomStreamingSupportedForTesting. This value gets cached hereamphtml/src/shadow-embed.js
Lines 328 to 331 in eccff2d
These tests would reset this flag in a beforeEach block, but this would not clean up this state for the last test in the section, causing hard to track test failures.
Moves the resetting of this state to an afterEach block instead, which seems to solve the problem.
