Currently, if a SpellCheckConfiguration is defined to enable spell check (see docs) and the platform the app is running on does not have support for spell check (e.g. web) or the spell checker connected to the enabled IME on the device is not supported, an assertion error will be hit (see examples: #34688 (comment), #119868 (comment))

This should be modified to instead allow spell check to fail silently and a warning can be added to warn the developer that it is being disabled in order to avoid hitting the error.
