Conflict: ion-refresher + ion-option-button in browser (v1.2.1)?

Ionic: v1.2.1
Windows 7
Chrome 47.0.2526.106 m

• Setup: Add an ion-refresher + ion-option-button to a ion-list (which reads data using ng-repeat)

• Behaviour observed in browser: ion-option button will not swipe. If ion-refresher is commented out then ion-option button functions as expected.

• I can reproduce this across projects.

• Test in Ionic Play does not demonstrate behaviour. Importing ionic Play files into local project reproduces behaviour.

Note: both ion-refresher and ion-option button work in Ionic View.

Can anyone else produce this behaviour?
