Hello folks,

Doing a right click on a flash object opens up a context menu as expected, but clicking on the entries has no effect. Can't change quality of a flash game for example.

It works fine in v1.7.x.
The attached .zip contains the newest pepper based flash plugin, a main.js and a package.json that might help you reproduce the issue.


System:
Win7 x64
Electron v1.8.x
Pepper Flash Plugin v26.0.0.151 x64
