Good work Caleb!
I don’t suppose there is any way for those of us without Chrome (and thus are using Android System WebView) to address this? I guess I could install (re-enable) Chrome for the time being and let the system use its rendering engine.
UPDATE: I tried this, but it unfortunately didn’t work: re-enabled Chrome, updated to the latest version, then set the flag to Disabled. Killed and restarted both Chrome and NewsBlur, but the rendering was broken. So, I disabled Chrome again and – so long as I don’t update to the latest Android System WebView – all is well again with the NewsBlur rendering. (If it matters, this is on a Samsung Galaxy S7 running Oreo.)
