swc_ecma_minifier bad case

[xc2]

Describe the bug

swc_ecma_minifier produces bad code when optimizing lottie-web with default config.

i've tested with the example "compress" and found that seems a69f172 introduced the issue.

Input code

https://github.com/airbnb/lottie-web/blob/63a39aeb27b8c13726ce9fcf850d9351b14be3e6/build/player/lottie.js#L10380-L10392

// input.js
// cargo run -p swc_ecma_minifier --example compress input.js

function renderShape () {
    var i;
    var len = this.animatedContents.length;
    var animatedContent;

    for (i = 0; i < len; i += 1) {
        animatedContent = this.animatedContents[i];

        if ((this._isFirstFrame || animatedContent.element._isAnimated) && animatedContent.data !== true) {
          animatedContent.fn(animatedContent.data, animatedContent.element, this._isFirstFrame);
        }
    }
}

renderShape();

Config

{}

Expected behavior

function renderShape() {
    var i, animatedContent, len = this.animatedContents.length;
    for(i = 0; i < len; i += 1)animatedContent = this.animatedContents[i], (this._isFirstFrame || animatedContent.element._isAnimated) && !0 !== animatedContent.data && animatedContent.fn(animatedContent.data, animatedContent.element, this._isFirstFrame);
}
renderShape();

Actual behavior

a69f172

function renderShape() {
    var i, animatedContent, len = this.animatedContents.length;
    for(i = 0; i < len; i += 1)(this._isFirstFrame || (animatedContent = this.animatedContents[i]).element._isAnimated) && !0 !== animatedContent.data && animatedContent.fn(animatedContent.data, animatedContent.element, this._isFirstFrame);
}
renderShape();
