How to change the font color of Theia

Recently I upgrade the theia version to 1.12.0, but it seems the font color does not fit well when the backgroud theme is black, the color of the file name is also black so I can’t see the file name very clear only if I click the file, it appeals like follows:


So I wonder how to chage the font color in the dark theme, for example, chage it to white. Thanks~

@LamYunfu if you reload the application does the font-color still look incorrect? If so, can you confirm there are no errors in the dev console?
