discMask.Dispose is not a function

Getting this error when opening Foobar on certain artists:

Error: Spider Monkey Panel v1.6.1 (Mini Player: CaTRoX: Mini player v5.0.0 by TheQwertiest)
discMask.Dispose is not a function

File: Module_Art.js
Line: 165, Column: 26
Stack trace:

Couldn't find any Dispose function in the Spider Monkey Panel documentation, so removing it seems to work.

Maybe could've been because of migration from 'foo_jscript_panel' to 'foo_spider_monkey_panel'?
