It seems that some online shops are trying to force the user to open the detail page of a product in a new tab. If you click the product while holding down the Ctrl key, the page will remain open in the current tab and you will have to explicitly use the context menu to do it.
What is the purpose of such a design? Do they want to deliberately discourage product comparison? I am always bored by these sites because I always compare several products at the same time. This has a negative impact on my experience.
