Add "no-scroll" option to aff-canvas minicart

Hello,

I hope you’re doing well. I wanted to point out a couple of things regarding the off-canvas feature. Firstly, it would be beneficial to have a “no-scroll” option for the minicart when it’s in off-canvas mode, similar to what’s available for the off-canvas item currently.

Additionally, I’ve noticed some quirks with the off-canvas minicart, especially when the sticky header is enabled. It tends to flicker while scrolling and sometimes disappears and reappears abruptly.

I’ve included a video to demonstrate these issues: Recording #84

Also, it would be convenient to have the option to disable the regular minicart in the sticky header. Currently, it remains open even when scrolling down, which isn’t always preferable.

For your reference, here’s another video: Recording #85

Thank you for your attention to these matters. Have a great day!

Best regards,

Jakub
