From some Canary updates, I have noticed that the Computed Values which used to come under the Styles Tab in Developer Tools now comes in its own new Computed Tab as seen in the screenshots.
Developer Tools as seen in Microsoft Edge Stable version 84.0.522.63
Styles tab seen in Developer tools as in Microsoft Edge Canary version 86.0.619.0
