Share button on release pages shows menu anchored at top-right instead of near button

Area: Android App
App version: 1.246.0 (build 906)
Device/OS: [Samsung Galaxy S9+ / Android 10]

Repro steps:
1. Open the GitHub Android app and navigate to any repository with at least one published release.

2. Go to the Releases tab and open a release page.

3. Locate the Share button (usually in the bottom-right area of the screen, near the bottom navigation or action area).

4. Tap the Share button.

Expected behavior:
A share menu / action sheet should appear anchored near or above the Share button you tapped (bottom area of the screen), with standard Android share options.

Actual behavior:
The share menu drops down from the top-right corner of the screen (near the toolbar / overflow area), even though no button exists there on the release page. This makes it feel disconnected from the tapped element and confusing to use.

Additional notes:
• This occurs consistently on release pages.

• A very similar positioning bug was reported in beta version 1.245.0 for the three-dot menu on release asset items (menu appearing in wrong position), which may be related or the same root cause (e.g., incorrect anchor view in popup/action sheet code).

• Workarounds tried: force close + clear cache (no change).
