This does not look related to DevTools, but rather the implementation of the dropdown element.  Does not reproduce on Mac.

Using the per-revision bisect providing the bisect results,
Good build:55.0.2874.0 (revision:)
Bad build:55.0.2875.0 (revision:)

You are probably looking for a change made after 421429 (known good), but no later than 421430 (first known bad).
CHANGELOG URL:
The script might not always return single CL as suspect as some perf builds might get missing due to failure.
