Years later, and this problem seems to still hang around.. Everything is updated to latest versions, cart page set properly, etc. Adblockers, scriptblockers, etc disabled also. Live Environment.

I am providing 3 images to help with my answer. ( I need to earn 10 Rep to be able to properly embed images in my answer/s)

• On attempting to click on the X button to remove the Cart item, it will show the link, but take no action with it.

Cart item showing remove link path for item to be removed

• Unless specifically halted via other scripts, the ability to right-click and then 'open in new tab' still exists;

The ability to right click and force the link via a new tab still exists

• After forcing the new tab, it performs the correct process of deleting the item from the Cart;

Forcing the link allows for successful deletion from the Cart

** I am aware that this particular solution is not ideal, and also not what a potential Customer would look to do, so we must find an actual solution within the code files. I have not yet looked into it properly, but when I do, I will be looking at how the Cart 'remove_item' object is rendered - is it a button, a link with image, etc, so then I will be able to properly overwrite it using a child theme of my Storefront. That way, when the Storefront theme is updated, it will not remove the change I made to the particular piece of code I have altered.

Also, we would not want it to open the link in a new tab, so this must also be taken into account.

Meanwhile, I do hope that the Storefront theme will actually fix this, but when I find the piece of code, I will share it here.
