Ionic crosswalk app crashes when I touch inside an iframe

Hello, I have recently created an ionic app embedding crosswalk (for retro compatibility constraints).

I use an iframe tag in one page. When this page loads I have no problem.
But when I touch inside the iframe (on input field or blank spaces) the app crashes (1 or two second after I touch).

I have my back to the wall …

I would know if someone have already got this issue?

May be Ionic team have you already got this issue ?

Thank you in advance for any reply
