Comment 23 for bug 1946599

So the problem is not with `LD_LIBRARY_PATH` or with how the sandbox parses its value to add readonly permissions, it is with a configuration file that's located in a place that the policy doesn't allow read access to by default, and which contains information for EGL to locate the right implementation to load.

In that light, and considering that we might see other similar bugs (caused by configuration files for certain libs not being readable) in the future, my suggestion in comment 15 seems to be a valid and future-proof solution.
