When the system fails to interpret the expression code,
it forcibly disables the feature per property.
This improvement enhances stability and performance
by avoiding reckless attempts to interpret JavaScript code.
When we confirm the full stability with expressions,
we can revert this code.
The current development of the expression engine is experimental.
It does not support multi-threading.
Therefore, when tvg::Initializer::init() is configured
with more than one thread, expressions will be automatically disabled.
