fix: fixed link color bug

[isxiaoxin]

The cause of the incident was that when I was using it, I found that if I first set a font size for the text, wrap the line at will in the middle of the text, then insert a link, and then modify the color of the link, it would not work.

After checking the source code, I can see that the font tag has the color attribute, but the a tag applies the browser's default color, but I remember that the color: inherit attribute would be set to the a tag when creating the tag. I guess that when executing document.execCommand ('foreColor', false, val), thecolorof the child element would be removed, causing this problem

So my modification idea is to create the link, get the selected a tag, and then add color: inherit to its style. After testing, this problem can be solved, and the output results are also very good.
