1869304 - The pages layout in print preview is not consistent, resulting in having contend displayed in incorrect orientation

Status: RESOLVED DUPLICATE of bug 1865172

(Core :: Print Preview, defect)

Description

[Daniel Bodea [:danibodea]]

Note

• The page following the one that is oriented in landscape, when in print preview, it appears orientated in landscape also, but with the content is in portrait mode (becoming somewhat unreadable).

Found in

• Nightly v122.0a1

Affected versions

• Nightly v122.0a1

Tested platforms

• Affected platforms: Ubuntu 22, Windows 10, MacOS 11
• Unaffected platforms: -

Steps to reproduce

1. Load print-test-first-page-landscape
2. CTRL+P
3. Observe page orientation in the print preview

Expected result

• Only the first page is displayed in landscape orientation

Actual result

• The first 2 pages appear oriented in landscape (although the second has its content in portrait, becoming somewhat unreadable)

Regression range

• Not a regression, but an implementation issue.

Additional notes

• This issue occurs when tested with Google account that was "opt-in" the native Firefox printing experience.
• If the issue is tested without having logged into a Google account that is opt-it, then all subsequent pages show up as oriented in landscape, while the content is oriented incorrectly.
• This is not an issue after print because the content is correctly oriented onto each page, only the page orientation in print preview being an issue.

Another STR to complete the demonstration:

1. Load print-test-second-page-landscape
2. CTRL+P
3. Observe page orientation in the print preview
   Expected result: Only the second page is displayed in landscape orientation.
   Actual result: The first 2nd and 3rd pages appear oriented in landscape (although the 3rd has its content in portrait, becoming somewhat unreadable)

:danibodea, if you think that's a regression, could you try to find a regression range using for example mozregression?
