Support custom dimensions for more tracking methods

[Starker3]

What happened?

As explained in the documentation here: https://developer.matomo.org/guides/tracking-javascript-guide#custom-dimensions It's possible to track Custom Dimensions with specific tracking requests instead of setting them globally and then needing to reset them before the next tracking request is sent.

However, this method does not work for any of the content tracking methods, such as: _paq.push(['trackContentImpression', 'Content Topic', 'More data', 'Other data', {dimension5: 'my dimension value'}]);

What should happen?

The Custom Dimension should be tracked

How can this be reproduced?

Use the above tracking method in your browser console and check the tracking request - no dimension parameter is sent and no custom dimension is tracked by Matomo

Might also be relevant for other tracking functions, thinking about trackContentInteraction, logEcommerceOrder, everything else sending a request.

Will relabel as an Enhancement as the feature is just not available at the moment.

I forgot to mention that I also tested with trackContentInteraction and it doesn't work there either. Didn't get a change to test with an ecommerce order.

We also just had a customer who would like to track custom dimensions for Ecommerce such as the currency to work around https://github.com/matomo-org/matomo/issues/3812

However, despite the dimension value being sent to the server, the dimension in scope action is not stored along the ecommerce conversion.
