我记录了一个错误，并同意它是一个错误，应该在版本80中修复.请参见

I logged a bug and got agreement that it's a bug, should be fixed in version 80. See https://bugs.chromium.org/p/chromedriver/issues/detail?id=3209 .

它确实与提交的插页式广告"有关，就像@pcalkins在评论中建议的那样，但是我找不到一种可验证地设置Chrome的http-auth-committed-interstitials的方法在C#中标记.

It does appear to have something to do with "committed interstitials" as @pcalkins proposes in the comments, but I couldn't find a way to verifiably set Chrome's http-auth-committed-interstitials flag in C#.
