composeHtml not allowed as property but received from thunderbird
Thunderbird 78.7.0:
Extension API: composeHtml is now exposed in MailIdentity
messenger.accounts.get(item.selectedFolder.accountId) returns object which contains property 'composeHtml'.
Using the object in call
messenger.exp_logout.exp_logout(result.identities);
raises exception from thunderbird check routine.
Better Solution: add property to logout_exp schema definition.
