Description

Hello, first let me thank all the contributors to this awesome firmware. I'm using it to create a custom keyboard used for accessibility purposes.

I was so thrilled to be finally be able to control my mouse again with simple keys (mouse layer).
It is working very smoothly.

However, as I am using oneshot mods on a designated layer (I have a very limited amount of keys), I noticed one thing: I was unable to use ctrl+click in my browser to open a link in a new tab.
To be clear and complete, I am using add_oneshot_mods with ctrl modifier along with a click on the MS_BTN1.
I did not try it with a conventional held modifier, but I suspect the same problem might be present.

I marked this as a Feature Request because I did not find a way to have that ctrl + mouse click behavior.
I am sorry if the feature exists, and I did not find it, or if this issue is a duplicate (did not find a similar one by myself).
Of course ctrl is just an example, I am generally talking about oneshot modifiers combined with mouse keys (as shift+click would also be useful when I need to highlight text).

Hope that you can help, thank you so much for your help.
I am willing to but a 50$ donation bounty to implement this feature (in case it is missing) into QMK if that is allowed.

The relevant code is in action_util.c, but basically .... mousekeys don't call send_keyboard_report which is what checks, applies and clears the oneshot mod status.

A simple option may be to edit action.c, and the "register_mouse" to also run send_keyboard_report. I'm not sure that will work, though, TBH.
