Context menu opening an EPUB directly with ACE

For the Microsoft PC Windows 11 22H2, ACE version 1.3.2,

It would be helpful to be able to right click (Open With ACE) and EPUB file and have ACE open and start evaluating that EPUB.

Currently it just open's ACE App but does not start the evaluation.
However, if ACE is already running, doing this right click open with ACE will start the evaluation.

Sounds like some timing issue and the parameters of which file to act on isn't happening when the App initially launches vs. when the app is already running.

No source files or tests are named. Start by tracing how the Windows “Open With ACE” launch argument is received when ACE starts, then compare it with the already-running application path. Done means a direct context-menu launch opens ACE and begins evaluating the selected EPUB, with the existing behavior preserved when ACE is already running.
