HammerModule does not work when imported before BrowserModule #37149
Description
🐞 bug report
Affected Package
This issue affects: @angular/platform-browser
Is this a regression?
This issue exists in version 9.0 and 9.1.7. The HammerModule did not exist before 9.0.
Description
A clear and concise description of the problem...If the HammerModule is imported before BrowserModule and BrowserAnimationsModule, it seems to have no effect.
🔬 Minimal Reproduction
stackblitz - notice that panning in the box does not log anything if HammerModule is imported before BrowserModule. If the order is switched, the component logs as expected.

Anything else relevant?
I was unable to find any documentation about this requirement when importing HammerModule, so I assume it is a bug. If it's expected, a simple documentation addition may be enough!
