bug(ios/app): Long-press options in the top row appear directly under finger

@caforbes reported the following from Slack

> Hi Keyman, we have a QOL bug report for iOS. It looks like longpress options in the top row do not appear above the row, they appear directly under your finger, which is weird. This comes from several users on the following devices: iPhone 12 mini, iOS 16.4.1(a) + iPhone XR, iOS 16.4.1 + iPad Air 4th gen, iOS 16.4.1(a)
>
> this was in the Keyman app, not the FirstVoices app (we were doing some local testing before releasing an update)
