"localScale depracated" is displayed on the console

[cx20]

I used the grimoirejs-text plugin and the following warning is displayed on the console.

localScale depracated
    get @ index.js:650
    (anonymous) @ VM7376:1
    get @ index.js:650
    _draw @ TextComponent.ts:69
    $mount @ TextComponent.ts:11

    _mount @ index.js:1968

    invoke @ runtime.js:299
    prototype.forEach.prototype.(anonymous function) @ runtime.js:116
    fulfilled @ index.js:3196

I think that it is probably caused by the following code.
