100% CPU usage when loading or reloading site pages about darkreader

[alexanderby]

Do you have any other steps to reproduce? Unfortunately it doesn't happen for me.

Thank you for trying to check it out.

I want to make a clarification.
Only one CPU core is always loaded at 100%.

I also checked on a super powerful gaming PC, the site loads quickly with your extension enabled. The load on one CPU core also remains 100%, but it lasts for several seconds (1-3), and if you do not view the load on each individual core (especially if there are 8 or more), you will not notice the performance problem.

But the described behavior was tested on a Mini-ITX PC, Intel Celeron 1037U processor (1.8 GHz, 2 cores).

Also, on this PC, none of the Chrome extensions, like the one for blocking ads, or other Dark Theme extensions (which I have tested, I can list them) have these performance issues, and do not load the CPU at all when loading the site I have specified and other sites.
I like your extension the most (out of all similar ones), because in most cases it does its job the best, so I decided to write to you about it, hoping that your extension can become even better.

If you have only a super powerful PC in your arsenal, then it seems that you will not be able to test this performance issue.
If you are not able to test this and solve the described problem, I would like to thank you for your work and the wonderful extension anyway.

Steps to reproduce the problem:

1. Chrome
2. Enable your extension.
3. Open the site I specified (or https://parcelsapp.com/en/tracking/LP00455472799295).
4. And a low-powered PC.
