I suspect the PR https://github.com/otcshare/chromium-src/pull/43 introduced this issue.

I checked this on my MacBook Pro 10.13.6 with the nightly build 5f58c3c, didn't see this issue:

I can reproduce this issue on https://github.com/otcshare/chromium-src/commit/4d20cb10246a81ccb21880da668f5f3d4615a5cb against macOS 10.14 on iMac (2017)

I can't reproduce this issue against macOS 10.14 on MacBook Pro (2017). Perhaps we can lower the priority.
