Regression : Static variable caching fails in subsequent compilations with compilation server

[R32]

After the first compilation with "comilation server", subsequent compilations will aways output false.

I'm not sure if this is the expected behavior.

Tested in haxe 5.0.0-alpha.1+765abfa

Main.hx

package;

class Main {
	static function main() {
		trace(Macros.test("hello world!"));
	}
}

Macros.hx

import haxe.macro.Context;
import haxe.macro.Type;

class Macros {

	static var cached_t_string : Type;

	public static macro function test( e ) {
		if (cached_t_string == null) {
			cached_t_string = Context.getType("String");
		}
		var t = Context.follow(Context.typeof(e));
		var r = Context.unify(t, cached_t_string);
		trace(cached_t_string);
		trace(t);
		trace(r);
		return e;
	}
}

build.hxml

-main Main
--js main.js

Starts comilation server:

haxe --server-listen 6000

Building in Cygwin (Because cmd.exe doesn't have touch command)

# First compilation
$ touch Main.hx && haxe --connect 6000 build.hxml
Macros.hx:15: TInst(String,[])
Macros.hx:16: TInst(String,[])
Macros.hx:17: true

# Subsequent compilations
$ touch Main.hx && haxe --connect 6000 build.hxml
Macros.hx:15: TInst(String,[])
Macros.hx:16: TInst(String,[])
Macros.hx:17: false

# Repeated compilations
$ touch Main.hx && haxe --connect 6000 build.hxml
Macros.hx:15: TInst(String,[])
Macros.hx:16: TInst(String,[])
Macros.hx:17: false

It's also weird that if you use VSCODE it always returns true, (maybe my vscode settings aren't right) but FlashDevelop outputs just like above.
