[Mellnik]

Describe the bug
A crash happens when opening a specific website.
https://webglsamples.org/aquarium/aquarium.html
The website provides WebGL examples. The crash only happens with the specific example in the link above.

To Reproduce
Steps to reproduce the behavior:

1. Open cefclient.exe
2. Go to https://webglsamples.org/aquarium/aquarium.html
3. Crash happens.

Expected behavior
No crash should happen. The website is a WebGL example.

Screenshots

Versions (please complete the following information):

• OS: Windows 11 23H2, 22631.4169
• CEF Version: 128.0.6613.120

Additional context
Reproducible with cefclient.exe and my embedded OSR application.
Not reproducible with Google Chrome.

The crash seems to happen by trying to add the capability "kLpacChromeInstallFiles" to so called "app container profile".
