Parsing docComment error for priority leaves trailing trimmable characters

[KennFatt]

Issue description

There is an error while parsing docComment.

I'm trying to declare @priority by this way:

/**

• @priority HIGHEST
• @param PlayerIllegalMoveEvent $event */

and HIGHEST also known as here. As we can see, HIGHEST has 7 characters (H, I, G, H , E, S, T) Remember this point.

• Expected result: Dumping '$tags["priority"]' must return valid string length and string value.
• Actual result: Invalid string value, i.e. "HIGHEST " or "LOW " and so on. It contains 1 space at the end, then string length are invalid.

Steps to reproduce the issue

1. Just fix the regular expression.

OS and versions

• PocketMine-MP: 49fbbea
• PHP: 7.2.3
• Server OS: Windows 10 64-bit
• Game version: PE and Win10

Plugins

• Specter (for testing), DevTools, and 1 plugin (Only contains Listener).

Interesting. I wonder if this bug was also in effect prior to subevent-handler merge.

I thought it was not a 'space' character there, because I've just tried to replace it with empty character and still error.
