Edge has been interfering with the web application experience from the start, with unwanted hover icons and menus that cannot be disabled by the application. (For example, if you hover over an image, you get Visual Search and Settings icons.) Super annoying.

But this latest change takes the cake. It is ugly. If the page has a scrollbar at document level, the web page will get rounded corner only at the top left, not the top right, thus losing symmetry. For example, go to CNN or Github. If the web page has dark-mode you get a distracting white border around the page, for example on chat.openai.com.

Edge is breaking this cardinal rule: Browser chrome belongs to the browser, but the content area belongs to the application alone. Edge should stay out of the content area, or at least should allow applications to turn off unwanted buttons and menus, thus retaining full control of the application experience.
