// The only reliable way to make sure that the iframe has the same dimensions

|
// work most of the time but will fail in various edge cases. Most reliable way
|
|
// is probably iframe-resizer package, but still with 40 unfixed bugs.
|
|
//
|
|
// Polling in our case is fine since this is only used when displaying plugin
|
|
// dialogs, which should be short lived. updateContentSize() is also optimised
|
|
// to do nothing when size hasn't changed.
