[4.x]: "Showing your unsaved changes." keeps popping up after not making any changes

What happened?

Description

I have a basic entry with just the default title field and a matrix field (that is limited to 1 item). Whenever I open an entry and just click anywhere on the page, the "Showing your unsaved changes." message pops up. If I discard the changes and click anywhere the same thing happens. If I save the entry and click anywhere, the same thing happens.

Steps to reproduce

1. Open an entry
2. Click somewhere
3. Message pops up wether or not I changed content

Expected behavior

The message shouldn't pop up when I don't make any changes

Actual behavior

The message of unsaved changes constantly pops up after I click anywhere on the page

Reproduce this with a basic entry containing the default title field and a Matrix field limited to one item. Check whether clicking without edits triggers the warning after opening, discarding, and saving; done means the warning appears only after actual content changes.
