遇到了极其诡异的不符合进入 if 条件的要求但是还是进入了

代码

    addFrontLine(_line_location_, _padding_, _border_) {

        console.log(_padding_);
        console.log(_line_location_);

        if (_padding_ >= _line_location_) {

            _padding_ = _line_location_

        }

        console.log(_padding_);
        console.log(_line_location_);

        const css = `

        .layout-tab-container .b3-list-item > .b3-list-item__toggle {
            padding-left: 4px !important;
        }

        .layout-tab-container ul ul:before {
            content: "";
            position: absolute;
            top: 0;
            bottom: 0;
            left: ${_line_location_}px;
            border-left: ${_border_}px solid var(--b3-theme-background-light);
        }
        
        .layout-tab-container ul ul {
            position: relative;
            padding-left: ${_padding_}px;
        }
        
        `
        this.applyStyles(css);
    }

执行后控制台输出的值

如果把 if 语句注释掉，就恢复正常了。 有没有大佬帮看看是什么原因？ 完整代码 https://github.com/zxkmm/siyuan_doctree_compress/blob/13f1b3cda6c721001c1c33ab449e6321bc791807/src/index.ts#L118
