Steps to reproduce the problem:
1. Install the extension Shortcut Manager
2. Make a New Shortcut to excute the js. The code is in the attachments.
3. Install the StrokesPlus which is a glogal mouse gestures app.The address is www.strokesplus.com
4.assign the shortcut which is built in the Shortcut Manager 
to StrokesPlus
5.use it on the google or other page which can be turned the page.

What is the expected behavior?
The page will go to next without anytime to wait.

What went wrong?
It's normal when I used Chrome 51.But when I update to the Chrome 52,I find when I excute the gesture to go to the next page,I need to wait 2~3s until the js begin to excute.It's not always,but most time is.Sometimes I don't need to wait.If I use the keyboard to excute the js directly,It's normal.
I tryied other Broswer which is built on the Chroumin52,It's also normal.
The Chrome 54 Dev also has this problem.
