我在Chrome中使用Tampermonkey腳本，該腳本增加了Gmail中「移至」和「標籤爲」菜單的最大長度。幾個月前，當Tampermonkey自動更新到最新的主要版本時，該腳本停止工作。幾年前，我們的開發經理幫助我編寫了這個腳本，由於我是一名開發者開發人員，我沒有很好的計算它爲什麼不工作了。更新後用於Gmail的Tampermonkey腳本問題

如果我檢查Chrome中的元素以打開dev控制檯，我可以看到Tampermonkey沒有注入新的值。如果我手動更改開發控制檯中的值，我可以生成我正在查找的結果。查看截圖在下面Imgur專輯（顯然我不能發表任何圖片或者兩個以上的鏈路，因爲我至少需要10聲譽...）
因此，大家可以看到，我能夠通過控制檯修改菜單的長度就好了。 Tampermonkey沒有這樣做，我猜這是因爲我腳本中的某些內容已經過時。任何幫助將非常感激。
