Easy

Brave version (chrome://version info)

Brave	0.55.12 Chromium: 70.0.3538.45 (Official Build) beta (64-bit)
Revision	cbdc32e4334458954e9def214d7e5fa1ca1960eb-refs/branch-heads/3538@{#830}
OS	Linux

Reproducible on current release:

• Does it reproduce on brave-browser dev/beta builds? Yes on Beta. Need to test on new Dev
• Does it reproduce on browser-laptop? No

Website problems only:

• Does the issue resolve itself when disabling Brave Shields?
• Is the issue reproducible on the latest version of Chrome?

@yrliou noticed that likely on startup we overwrite the global shield setting, so I think work @pilgrim-brave is doing in #1449 will fix this.
