This fixes a bug introduced in React 16.6.0, which was not present in 16.5.2.
Runtimes without
setTimeout
andclearTimeout
(e.g. ClearScript for .NET) are now crashing just by importingreact-dom
.This replicates the fix for
scheduler
introduced in #13088 forreact-dom
, by checking for existence ofsetTimeout
andclearTimeout
in the runtime before using them.
