Steps to reproduce:

1. Open Word 365 with UIA enabled (default)
2. Type some text

Actual behavior:

Many occurences of "MathPlayer 4 not available" warning in the log

Expected behavior:

No warning, or at least on a lower level.

Context

mathPres.ensureInit is called in getTextWithFields. I believe this should be avoided, as this method is called many times.
Ideally, math should be initialized at NVDA startup time.
@michaelDCurran pointed out that this means that installing Math Player requires a restart of NVDA to work, but I don't think this should be a show stopper. I guess it makes common sense that installing dependency x of product y requires a restart of product y.

System configuration

NVDA installed/portable/running from source:

Installed
