Brave version (brave://version info)

Brave Dev	0.57.3 Chromium: 70.0.3538.67 (Official Build) dev (64-bit)
Revision	9ab0cfab84ded083718d3a4ff830726efd38869f-refs/branch-heads/3538@{#1002}
OS	Windows 10 (Build 18262)

Brave	0.55.20 Chromium: 70.0.3538.67 (Official Build) (64-bit)
Revision	9ab0cfab84ded083718d3a4ff830726efd38869f-refs/branch-heads/3538@{#1002}
OS	Windows 10 (Build 18262)

Reproducible on current release:

• Does it reproduce on brave-browser dev/beta builds?
  • This occurs on dev and stable

Website problems only:

• Does the issue resolve itself when disabling Brave Shields?
  • No
• Is the issue reproducible on the latest version of Chrome?
  • No. Chromium (71.0.3576.0, not Brave) behaves correctly.

Additional Information

Also tested with GitHub, Google, and Login.gov (which uses WebAuthn) with the same results.

I installed regular Brave just to test, so it's a fresh install.

I am also aware of #324, but unlike that issue, there are no errors in the console and prompts seem to run forever or until they time out instead of being interrupted.
