ng2(x)-currency-mask doesn't work on android web view.

[wangshu3000]

We used currency mask, but it doesn't work well on android Oreo web view.
User can input any characters, but it can not be formatted, looks like the event (like keyPress) couldn't be triggered on web view.
On web view, onInput event would work.
We have enabled JS for webview.

We found a solution to fix it form android side. But we should also be able to fix it from ngx-mask side.

It works well on all other platform, ios, ff, chrome, safari, IE, or chrome on android. Only not work on android WEB VIEW.
