Affected versions

Affected platforms

  • Windows 10x64

Steps to reproduce

  1. Launch FF.
  2. Trigger the new Print UI modal.

Expected result

  • The count buttons from Copies section are properly contained in borders

Actual result

  • The Count buttons from Copies sections are missing the upper Border.

Suggested Severity

  • Seeing as how this issue is OS specific, and a minor UI issue, I would recommend it as an S3.

Regression range

  • Not a regression.
Severity: -- → S3
Priority: -- → P3

We've fixed this in the print UI by implementing a custom number picker.
But it is a valid bug for the default type=number / stepper widget, e.g. the example on
Depending on the scaling, the upper and/or lower borders are gone.

Severity: S3 → --
Component: Printing → DOM: Forms
Priority: P3 → --
Product: Toolkit → Core

Given comment 1, we won't track for printing.

However, it probably belongs in Layout::Form Controls.
