Small CSS change to spec documentation for ease of use

[FredGandt]

The documented tables of named character references show the characters in cells subject to the following CSS:

#named-character-references-table > table > tbody > tr > td:last-child:hover > span {
    position: absolute;
    top: auto;
    left: auto;
    margin-left: 0.5em;
    line-height: 1.2;
    font-size: 5em;
    border: outset;
    padding: 0.25em 0.5em;
    background: var(--bg, Canvas);
    width: 1.25em;
    height: auto;
    text-align: center;
}

The result is that upon hovering over the characters, they are enlarged and moved to the side, presumably for a better view, which is quite helpful. However, if the cursor is moved toward the character, perhaps to select it for copying, the above rule disengages and the character retreats to its former diminutive station, which is quite annoying.

A small change to the CSS rule fixes this issue, while the "zoomed view" feature remains in place:

#named-character-references-table > table > tbody > tr > td:last-child:hover > span {
    position: absolute;
    top: auto;
    left: auto;
    margin-left: 0.2em; /* <-- this small change */
    line-height: 1.2;
    font-size: 5em;
    border: outset;
    padding: 0.25em 0.5em;
    background: var(--bg, Canvas);
    width: 1.25em;
    height: auto;
    text-align: center;
}

Please consider applying this small change.
Thanks.
