bug(Slider): Page Up/ Page Down buttons increase value but not by 10 steps

[teodorachiosa]

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

14.2.7

Description

According to the documentation, the slider should increase the value by 10 steps when using Page Up/Page Down keys.
It instead increases/decreases by a different number of steps.

Reproduction

StackBlitz link: 500 Internal server error for Stackblitz.... but the issue can be reproduced on the official Material demo
Steps to reproduce:

1. Go to: https://material.angular.io/components/slider/examples#slider-configurable
2. Type '9999' as the max value
3. Use the Page Up/Page Down keys to increase/decrease value

Expected Behavior

The value is increased/decreased by 10 steps.

Actual Behavior

The value is increased/decreased by 1000 steps for max value 9999,
the value is increased/decreased by 100 steps for max value 1000,
not by 10 steps, like in the documentation.

The step is not set, so I assumed a default of 1 x 10 = 10 steps.

Using the arrows, the value is increased/decreased correctly, by 1 step.
Happens on both angular 15 and 16.

Environment

• Angular: 15.2.9
• CDK/Material: 15.2.9
• Browser(s): Chrome
• Operating System (e.g. Windows, macOS, Ubuntu): Windows

I suspect this may be intentional and the documentation is just out of date (incrementing by 10 doesn't get you very far in a slider with 1k steps). The WAI ARIA docs don't prescribe a specific increment for page-up/page-down, just that it should be more than regular up/down.

+1 to what @mmalerba said. This behavior was not added to the slider by us. It is the behavior of the hidden native <input type="range" that is being used under the hood
