Mobile web UI: Privacy popup does not appear when tapping the privacy button on the Boost Confirmation dialog

[neatchee]

Steps to reproduce the problem

1. Using a mobile device, go to your instance URL
2. Go to Preferences => Appearance
3. Enable the "Show confirmation dialog before boosting" option
4. Go to any timeline
5. Tap the boost icon
6. In the popup confirmation screen, tap the globe (post privacy) button

Expected behaviour

Privacy dropdown appears, allowing the user to change the privacy of the Boost

Actual behaviour

The privacy button changes as if it's selected, but no dropdown appears

Detailed description

When the "Show confirmation dialog before boosting" option is enabled, the mobile UI does not allow changing the privacy of the boost, because the dropdown doesn't appear after tapping the privacy button in confirmation dialog.
