Unhandled rejection ERR_FEATURE_NOT_AVAILABLE_ON_PLATFORM (recursive watch)

[Anonymous-BCFED]

I receive the following exception when running Ungit on my desktop Ubuntu 20.04 environment. This doesn't appear to actually break anything, so I guess it's a warning of a very noisy kind? Changes to the FS do seem to go unnoticed until you manually refresh, though.

$ ungit
## Ungit started ##

Ah yes.... so Ungit uses nodes fs.watch() and it is famously doesn't support linux and yes this is just a warning.

If I remember correctly, ungit will not be able to detect some of the file changes correctly when you see this message and relies on period automatic reload ungit does

same on arch linux worked fine before, but now it's broken. I haven't noticed which update broke ungit, maybe related to latest nodejs update?

This doesn't appear to actually break anything|

For me it breaks ungit on any git repo completely. Can open folder which is not git repo, but if .git folder exists - ungit crashes :c
