Plugin conflict with Leadpages

Hi
I have found a plugin conflict with the leadpages connector plugin and the OneSignal plugin. I have been in contact with leadpages support and there message is:

According to the dev team, they would recommend checking with OneSignal regarding this. They’ve noted the conflict and if we update the plugin in the future it may be something we look into, but at the moment this is the only reported instance of this conflict they have received. They prioritize these reports based on many factors including; severity of the issue, the number of customers it affects, the priority of other issues in the queue, etc.

Here is the video of the bug:
