Bug? B4A didn't check library methods

[rdkartono]

On B4A 10.5, it didn't check library methods , available or not. Notice that it didn't show red underlines although Play method not available

On B4J 8.80, it check correctly . Notice red underlines showed when Play method not available

I can only guess that there was a different error somewhere and it didn't reach that error. If I'm wrong then please post a small project that demonstrates it.
