Now, as per reliable sources, it seems that the early build of the next version of Microsoft Edge has been given this feature. It has not been enabled by default, but can be toggled on if desired. There are some beta testers who have not yet seen this feature in their beta builds, but that is to be expected as Microsoft will not want to push this feature to everyone just yet.
However, this feature, while exciting, does come with a warning. Usually, when there is a new software update, be it for an app or an operating system, there are bugs or unresponsive elements. If you go for the update ASAP, there is a chance that you may see some of these bugs and also face some crashes.
