Post with small message on iOS cannot be closed in v7.0.3

**Describe the bug**
after migrating from version `6.0.2` to `7.0.3`, small messages cannot be closed inside iOS app and UI is blocked (only way to close the `small` message is to kill the app)

**To Reproduce**
Steps to reproduce the behavior:
1. Install `"capacitor-community/intercom": "7.0.3"`
2. init intercom user in the mobile app and close the app
3. From intercom dashboard, create a "Post", use message size `small`, put your mobile user in the audience
4. Open the app (or trigger the post from the app)

-> Small message is shown
-> Small message cannot be closed (no error in the JS context, and no error on XCode). App is blocked until you kill it and reopen

with message size `large` this does not happen, and on previous major version (6.0.2) this does not happen as well for small messages

**Expected behavior**
Small message can be closed and user is not blocked
