The charitable view would be that they come from language/platform that does include the base-class's methods/apis.
Your example of dotnet/C# doesn't seem to be the best - DotNet/C# repeats the base documentation - for example the SaveFileDialog class [1] lists all of the methods but indicates when the methods come from the base class.
Flutter also seems to list inherited methods - for example the TextButton [2].
I liked Edge originally too - it seemed cleaner than chrome and had some cool features like vertical tabs and the Dev tools that were better than Chrome's. I made it my daily driver.
Then they adding a shopping helper; then more ads to the new start-page; then a notification about Microsoft rewards; then popups about how "Bing is better" or that "Bing AI" was there to help - don't forget the "Open links in Edge on Mobile" popup; then they added a side toolbar with a giant B[ing] button that wasn't removable unless you toggled a group policy (now there's an option for it). The damn button was the last straw for me because of the amount of work I needed to do to just disable it.

Yeah, so do I and Edge kept getting in the way to keep telling me about all the new things that Microsoft things I should use.
Chrome isn't great - the privacy sandbox/built-in interests stuff is disgusting - but Chrome wasn't as "in your face" so I could just start it and go. Brave avoided the the privacy sandbox and now Firefox works for me everywhere.
I find the best middle ground is setting up the IDE to have TSC watch running while making changes, but using other tools for doing the actual compiling (vite for example). This allows me to refactor quickly - choosing when to ignore type errors - but also be notified of all the other call sites that I need to update, including in all of the files not currently open in the editor.
