broken link on iPhone

Opened #1531.

I could not reproduce this on an iPhone, but the code has a clear way to produce exactly the reported symptom. openFeedback() reaches into the widget's iframe and clicks the button inside it, unguarded at every step:

const launcherFrame = document.getElementById("launcher-frame");
const button = (launcherFrame as HTMLIFrameElement).contentWindow.document
    .getElementsByClassName("launcher-button")[0];

If the widget hasn't loaded — blocked, slow, or stopped by tracking protection, which is the usual story on iOS — launcherFrame is null and this throws. The menu item does nothing, and the only trace is a console error the user never sees.

The PR guards each step and falls back to a mailto: so the button is never a dead end. If the widget is in fact loading on that phone, the cause is elsewhere and this only removes a way for it to fail quietly — so I've left it as Refs, not Closes. If you can get a console log off the device, that would settle it.
