Reproduction Steps

1. Download dyn_menu.lua from tsl0922/mpv-menu-plugin and place it inside ~/scripts.
2. Download the example menu configuration file, input.conf, from tsl0922/input.conf and place it inside the portable_config directory.

Expected Behavior

Following the merge of right-click context menu support (#13700), dyn_menu.lua alone should be enough for context menu functionality, without needing menu.dll or dialog.lua to be placed into the ~/scripts folder

Actual Behavior

In the latest mpv builds (GitHub CI, shinchiro Windows build, and zhongfly):

• The context menu only partially works with the dyn_menu.lua script from the main branch. Right-clicking does bring up a context menu, but clicking options like Open > Files, which should open a file selection dialogue, does not work. This functionality seems to require all three files present in the ~~/scripts directory, contrary to the expected behaviour.
• Additionally, using the dyn_menu.lua script downloaded from the GitHub releases page results in the context menu failing to display altogether.

Log File

output.txt

Sample Files

No response

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

like Open > Files, which should open a file selection dialogue

File open dialog is not implemented/supported. Only context menu is supported. Patches welcome, there is currently no plans to add this.

Really? I distinctly remember it working when the feature was first merged. I also remember it working a couple of months back, but I can't exactly pinpoint the time frame because I haven't been watching stuff lately. Let me downgrade to older versions and see if I'm right.

It seems I was mistaken; the open dialogue functionality was indeed never implemented.
