(Core :: Graphics: Color Management, defect)

Description

[Optional Real Name]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

1. get a color managed windows x64, like Win7 x64 (probably not necessary, depending on FF CM methods)
2. Install FF 69 for x64 or any ver. since 2019
3. Configure FF according to https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/3.5/ICC_color_correction_in_Firefox
4. Go to ICC "must pass" official browser test:
   http://www.color.org/browsertest.xalter
5. Go to partial features test at
   http://www.color.org/version4html.xalter

Actual results:

Mandatory test at step 4 is failed.
Test at step 5 shows that V4 ICC profiles are ignored, while ICC V2 profiles are honored.

Expected results:

both tests at steps 4 and 5 should be passed, indicating correct color management.
For reference, a mature browser, like Internet Explorer, should be taken, which passes all the rendering tests.
