@Tonev is this a duplicate of #18234?

@bsclifton

I think Reader mode and Speedreader are two different features. I tested the bug, filled by @stephendonner, and the behavior there is a bit different to what I'm describing in this bug report. I just included video recordings in the other Github ticket, please take a look at them, so we can determine whether we're talking about the same bug (duplicate) 👍

@iefremov

Are you sure it's a duplicate? After @bsclifton asked if this was a duplicate, I provided video recordings about my report and @stephendonner's report.

I also thought this wasn't a duplicate after @bsclifton didn't close it as such, and @stephendonner and @rebron labeled/moved the report.

my bad @Tonev , I've completely missed that comments - reopening. FWIW, i wasn't able to reproduce both issues on Beta

@iefremov

I was able to easily reproduce the issue on Release, Beta, and Nightly.

1. Ensured Speedreader was disabled via brave://settings/appearance.
2. Opened https://brave.com/blog/.
3. Clicked on the Reader mode icon in the address bar.
4. Ensured the Reader mode icon disappeared.

Reloading the page brought back the Reader mode icon on all Release, Beta, and Nightly but then encountered the following bug: #18242.

I will update the report description since this bug is reproducible on all Release, Beta, and Nightly nowadays.

Confirmed that the Speedreader icon not only persists after initial click (to enable the feature), but exists as a working On/Off toggle of the reader mode.
