Describe the bug
In Firefox, the zoom feature uses transform styles (see storybookjs/storybook#12845) - unfortunately this breaks positioning on elements that require position: fixed when in the "Docs" view.

Normally a position: fixed element's position would correspond to the viewport but in Firefox it corresponds to the element with the transform style.

While writing string data (example = "121212121212121" -> string of all integer characters) into excel.
while user download and see, the downloaded xl/CSV, the data is shown in exponential format. Is there a way to show the same data. without converting into exponential in this case.

Feature Description

I can set the animation duration for the tabs themselves using animationDuration on the mat-tab-group. If I set this to 0, the tabs switch instantly, but the ink bar moves across taking 500ms, which makes the tab switching look slower than it actually is.

I can implement this myself using ng-deep:

::ng-deep .mat-ink-bar {
