Subject: [PATCH] `WebGLPipeline.hasBooted` is a new boolean property that
 tracks if the pipeline has been booted or not, which is now far more
 important in 3.5 than in previous versions. This is checked in the
 `WebGLRenderer.addPipeline` method, and if not set, the pipeline is booted.
 Fix #5251 #5255
