1720382 - In Print Preview, ctrl+mousewheel unexpectedly works to do full-page-zoom, specifically for same-origin iframes

Status: NEW

(Core :: Print Preview, defect, P3)

Description

[Daniel Holbert [:dholbert]]

STR:

1. Load this data URL testcase:

data:text/html,Try to zoom with Ctrl (or Cmd) and mousewheel<br><iframe src="data:text/html,hello">

2. Ctrl+P to open print preview
3. Hover the iframe inside the print-preview rendering, and hold Ctrl and spin your mousewheel (to attempt full-page-zoom)

ACTUAL RESULTS:
The iframe content ("hello") -- and only that content -- zooms in/out with your ctrl+mousewheel action.

EXPECTED RESULTS:
Nothing should happen when you do Ctrl+mousewheel. Printed pages don't support full-page-zoom; you zoom them using the print settings.

Hmm, maybe you should argue about this with smaug (bug 1661691). ;-)
