I tried the vivaldi workaround.Really liking it so far. Have improvised a bit. Attaching gif for a demo of what this workaround looks like.
If anyone is interested, you can download vivaldi portable version Using a standalone version of Vivaldi | Vivaldi Browser Help
and replace ‘User Data’ folder with mine and you will have identical setup to the gif when you launch vivaldi.exe.
My User Data Folder: My Files
P.S: ctrl+F11 removes all Vivaldi UI elements and gives the clean desktop app look.
