{{picture::*}}-Inserttag not using width and height parameter

Using the Picture-Tag I have noticed that, even if there are width and height parameters passed, the image will be displayed with it's natural width and height.

{{picture::[imageOrUuid]?width=800&height=400&alt=sometext}}

Will ignore the passed width and height and use the images natural size.

Upon further investigation I have found that in
https://github.com/contao/core/blob/3e41ad8718f6dea9c10c8a9b0341ed86f2bbe2ae/system/modules/core/library/Contao/InsertTags.php#L1040
The Picture::create is being called with 0-values as $width and $height.
This seems to be a bug as the documentation states, that width and height parameters can be passed to {{picture::*}}.

The documentation is actually wrong. The {{picture::*}} insert tag only supports size, alt, class, rel, and template, see contao/core#7635.

{{picture::*}} is meant for responsive images, which needs a size ID instead of width/height. If you want to pass width and height you should use the {{image::*}} insert tag.

This should get fixed in the documentation.
