Not a problem to be dismissed lightly .. throw enough water into the intake and the flame might just go out ....
As a f'rinstance .. there were some problems with a well known engine on a well known Type around 15-20 years ago where this is precisely what happened ... on more than one occasion with, as I recall, at least one dead stick landing (?) ... ignitors notwithstanding.
Fix was to change procedural limitations so that minimum RPM requirements could address the problem .... never mind the problem in descent profile planning halfway down the slide when one needed to run the engines up to the relevant N1 upon encoutering unexpected heavy rain ....
