Fails to deobfuscate script obfuscated with js-confuser

[MDMCK10]

synchrony version: 2.4.0

issue description: When attempting to deobfuscate a script that has been obfuscated with https://jsconfuser.com/ (tried both medium and high presets), the script is not properly deobfuscated.

expected result: something that at least contains the main part of the original code, in this case: console.log("testing 1234")

actual result (used medium preset): a script that does not appear to have been fully deobfuscated, see here: https://privatebin.net/?3c9844bacd1dfbc6#5AxRmxoakTsaSpR1qdGci5gFCegFhuF1tLyxwUuuuSnm
