Recently on the latest chrome browser, when adding css using inspector-stylesheet by clicking the '+' button with !important; on it, the inspector-stylesheet shows it as !important;!i;!; instead of !important;
Here is the screenshot of the issue. I have tested this on multiple laptops both Macbook and Windows.
My chrome version 131.0.6778.205 (Official Build) (x86_64)
This issue is fixed and scheduled for stable release early April.
