The Bugbug bot thinks this bug should belong to the 'Core::DOM: Core & HTML' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I follow the same setup in comment #0, see attachments.
But I could not reproduce the issue.

Hi Mohammad, does the attached test page matches your? If not, could you provide the link or a test page that shows the issue, so we are able to reproduce it. Thank!
