As you can see there is a leading space before toc items.

Compare these two images:

you can find that the css settings of span tag seems the reason.

But I check the css style settings can’t find the related css style.
So I ask for help here

Here is the css styles

    -webkit-text-size-adjust: 100%;
    --palette-radius: 5px;
    text-rendering: optimizeLegibility;
    -webkit-font-smoothing: antialiased;
    word-wrap: break-word;
    fill: #aaaaaa;
    font-size: 20px;
    line-height: 24px;
    font-family: 'Monaco', 'Hack', '上首水滴体';
    font-weight: 500;
    -webkit-user-select: inherit;
    color: #8b8aed;
    box-sizing: border-box;

I think thay you have discover a issue in some part of toc macros. tiddlywiki.com has the same issue. It looks like a problem with hardcoded spaces in any toc macro(s), becuase the inspector of firefox show this space between button and text, both inside the a tag.

A temporary solution can be add \whitespace trim in each toc macro. Because I have looked at it quickly but without luck.
