Save & Continue loses cursor position

When editing page, "Save & Continue" saves page and reloads editor page in browser, resulting in losing of cursor position in edited text (opens edit page just like we pressed Edit button while viewing the page). That makes this button useless.

That is not only in WYSIWYG mode.

Side effect: when checking "Auto save every N minutes" - page reloads upon autosave just like with save&continue, losing cursor position, and autosave checkbox unchecked after reload, this makes autosave useless.

Suppose that save&reload should do more smoothly, without reloading page in browser, like it was in older versions.

P.S. I've upgraded from old version: 8.4.5 -> 11.10.3, there was no such problem in 8.4.5. I removed permdata directory before before starting new version.
