Chrome Version       : Version 53.0.2785.116 m (64-bit)

         IE: OK

What steps will reproduce the problem?
(1) Application Page whose style is applied on the execution of a JavaScript 
Publish/Subscribe event
(2) On the first occasion the page is rendered, the event is processed correctly and the styles are applied.
(3) However, on subsequent page loads, the styling is not applied as the event
is either not being fired/event is being fired and the synchronization of the 
event processing is not correct.
(4) This leads to the styling not being applied to multiple application
pages on an intermittent basis.

What is the expected result?
Styling is applied to the application pages on a consistent basis based on
the events being fired and processed correctly.

What happens instead?
Styling is applied to the application pages on a consistent basis based on
the events being fired and processed correctly.


Please provide any additional information below. Attach a screenshot if
possible.
The styling is being applied correctly on all Chrome versions prior to Chrome 53. We have also taken the current beta channel (54) and it also does not work on that version. However, the issue seems to have been resolved in Chrome 55 (current dev channel).

Have any changes been made to the way Java Script events are being handled in Chrome 53 which did not exist in Chrome 52 and have been reverted in Chrome 55?
