Adding a `sidenote` in a list item makes the main column narrow

[quxiaofeng]

For example,

{% math %}{\bf \lambda}^{(t+1)} \leftarrow {\bf \lambda}^{(t)} + \rho({\bf D\beta}^{(t)} - {\bf \gamma}^{(t)}){% endmath %}

Same algorithm applies to a general regularization matrix {%m%}{\bf D}{%em%} (generalized lasso)

is rendered as follows:

The sidenote is rendered in the env of <ul><li><p></p></li></ul>. The width is computed within the <p> env, which is only the main column.

The problem arises when blank lines are separating list items. The Jekyll engine parses them differently. See the discussion here

In the index page, if the abstract of the post includes a list (<ul><li></li></ul>), the abstract would be still rendered as <ul><li><p></p></li></ul>.
