Improvements and fixes for PC

• We have fixed an issue causing a large blank space to appear between the address bar and web content after the address bar moves back to the top when opening a new tab in Microsoft Edge.
  
• We have updated Narrator Scan mode for table navigation to now support CTRL + ALT + HOME to go to the beginning of the table CTRL + ALT + END to go to the end of the table.
  
• Microsoft Edge now supports the CTRL + O keyboard shortcut for setting focus to the address bar.
  
• We fixed an issue resulting in Sketchpad and Screen Sketch crashing after trying to change the ink color twice in a row when the ruler was visible.
