Home panel disappears when clicking Home button

Summary:

Home / start screen panel minimum height collapses to a ~1–2 pt “sliver” when the main project window is reduced to a thin title-bar strip.  Product Adobe Premiere Pro (macOS), recent 26.x builds.

Steps to reproduce:

• Open a project so the main edit / project window is visible.
• Manually resize the main project window height as small as Premiere allows (title-bar / thin strip).
• Open Home (Home button / start screen) so the Home panel appears as a floating window.
• Observe Home’s height.

Expected:

Home’s minimum height should be at least the height of Home’s own top icon / header chrome, regardless of how short the main project window is.

Actual:

Home often opens as an extremely thin strip (~1–2 pt), effectively unusable, until the main window is made taller.

Why this matters macOS Accessibility clients (and power users) can resize Premiere windows shorter than typical AppKit minimums because Premiere allows near-zero content height. That is excellent for workspace management.

Home’s min-height coupling to the main window undoes that benefit and creates a trap: reduce the main window, then Home becomes a sliver.

Suggested fix:

• Decouple Home’s minimum height from the main project window height.
• Clamp Home’s minimum to the intrinsic height of Home’s top header / icon chrome (the same chrome users see when Home is a normal floating panel).

Workaround today:

Keep the main project window slightly taller than a pure title-bar strip before opening Home (so Home’s min-height stays usable).
