[iPad][Safari] A blank space appear on the page with initial-scale=1.0 when the screen orientation is changed

I have a page with the following meta tag: <meta name="viewport" content="width=1085, initial-scale=1.0">. When the user changes the screen orientation (portrait/landscape), a blank space appears on the right. However, if I remove the "initial-scale=1.0" from the meta tag, everything works fine without any blank space.

Steps to reproduce:

  1. Create a page and add the meta tag with initial-scale=1.0 (or just add the meta tag with initial-scale=1.0 to any existing page).
  2. Open the page in portrait screen orientation (make sure everything is OK).
  3. Change the screen orientation to landscape (make sure everythig is OK).
  4. Change the screen orientation to portrait - a blank space will appear on the right.

Expected result: The page will adjasted according to the new orientation.

Actial result: Blank space appears on the right.
