Cannot use intelephense php LSP - not found in $PATH

[artfulrobot]

Summary

The docs say that if intelephense is installed on the system, it'll find it and use it. But it's not finding mine even though it's in my $PATH

Reproduction Steps

I have installed intelphense as per the instructions. I have the flatpak of helix installed.

rich@dove:~% which intelephense
~/nodejs/bin/intelephense                 ➊
rich@dove:~% echo $PATH
/home/rich/bin:/home/rich/bin/local/dove:/home/rich/.local/bin:/home/rich/.cargo/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/rich/.bin-pdf:/home/rich/nodejs/bin ➋
rich@dove:~% flatpak run com.helix_editor.Helix --health php
Configured language server: intelephense
Binary for language server: 'intelephense' not found in $PATH ➌
Configured debug adapter: None
Highlight queries: ✓
Textobject queries: ✓
Indent queries: ✓

1. intelephense is found by the CLI
2. $PATH includes the dir where which finds the binary.
3. Helix can't find it.

Helix log

~/.cache/helix/helix.log doesn't exist. According to --help, the default log location is also empty (as in: I deleted it, I ran the command above, and it's still not there, so I assume nothing is logged).

Note: I'm not using ~ in my $PATH (I read there were problems)

Platform

Linux (Fedora 38, Flatpak)

Terminal Emulator

gnome-terminal

Helix Version

helix-term 23.05

I've just tried the AppImage one and it doesn't have a problem finding intelephense. So this is an issue affecting flatpak users.

This is probably an issue with flatpak's sandboxing. I'm not really sure how configurable that sandboxing is, maybe access to binaries installed on the host can be configured in the flatpak manifest upstream? https://github.com/flathub/com.helix_editor.Helix

sounds likely.
