Watcher not working with certain folder

[ArkhipovK]

From some point of time (idk exactly when the bug had appeared) watcher ignores any changes in folder. No errors, nothing happens at all.
Here is config

"watcher": {
        "files": "public/**/*",
        "autoUpload": true,
        "autoDelete": true
 }

But when change config like this everything works again.

"watcher": {
        "files": **/*",
        "autoUpload": true,
        "autoDelete": true
 }
