1834944 - Resetting zoom to "Actual Size" is broken in reader mode and pdf mode

Status: NEW

(Toolkit :: Reader Mode, defect, P3)

Description

[Austin Donisan]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/113.0

Steps to reproduce:

Open a news article and enable reader mode
Increase the zoom
Attempt to reset the zoom, either with the View -> Zoom menu or a keyboard shortcut

Actual results:

Nothing, the "Actual Size" item is disabled in the menu and the "Ctrl+0" shortcut doesn't work.

For PDFs weirdly the menu item is disabled, but the "Ctrl+0" shortcut still works

Expected results:

The zoom level should reset to 100%

I partially noticed this a while ago, but I assumed the change was intended. While debugging bug 1833494 I realized that these are regressions caused by bug 698873.

The Zoom In/Out menu options also don't get disabled in the UI when the zoom level is maxed out in Reader and PDF modes. I'm uncertain if that should be a separate bug, or fixed alongside this issue.

I've reproduced this issue in Nightly 121.0a1 and Firefox 119.0.1 on Windows10 x64.
Setting as NEW.
