The hidden anchor has size, the title cannot be aligned to center correctly

[Colin-XKL]

I was trying to add a framed text at top of my website homepage, just as #270.
But when I add a H1 title, the text cannot be aligned correctly. I checked in the dev mode, and found that there's an invisible element that has size, so that the title cannot be aligned to center correctly.

After deleting this invisible anchor node, the text displayed correctly, right at the center of that line.

Could you plz have a look at this problem? It's so annoying 😂
