px-alert-message will hang in Windows Firefox

[clementchi]

The following loop is running forever in Win Firefox and cause firefox to show the stop long running script popup.

// the following code is always true in Window Firefox
while(messageDiv.scrollHeight > messageDiv.offsetHeight) {
....
}

I think adding a threshold will stop the compare
while((messageDiv.scrollHeight - messageDiv.offsetHeight) >=** this._threshold**) {
.....
}

Hi @Menkhaus-ge - if you could take a look at this issue @clementchi would be very grateful!

The issue ended up be with the line height. We adjusted the sass to fix this bug.
Fixed in release 0.5.1
