Hi @Johnathan Magalhães,
I tried to log in to Microsoft Identity Manager, and my views looked normal (as shown below) and there was no icon overlap. My Edge version is also "128.0.2739.42". So, please try clearing your browser’s cache firstly and navigating to Control Panel>Programs>Programs and Features, find Edge and click Repair Edge. You can also try to see if this issue also occurs in other browsers and channels such as Edge Beta, Edge Dev, Edge Canary.
