Steps to reproduce

1. Open the new migration window and select Bookmarks from HTML file.
2. Import the .html file.
3. Import again using the Bookmarks from HTML file option and observe the importing window.

Expected result

• Previously imported number of bookmarks is not displayed.

Regression range

• Not a regression, it started happening with the implementation of Bookmark importing from HTML files (bug 1833427).

Additional notes

• Attached a screen recording.
• This is very hard to be seen on fast computers due to importing speed. It’s most visible on low-end computers.

:atrif, if you think that's a regression, could you try to find a regression range using for example mozregression?
