FileInput does not have stapled line in FastListTemplate

[MarcSkovMadsen]

Panel: Current master branch after 0.11.3
Bokeh: 2.3.1

The FileInput used to look like below when using in the FastListTemplate.

But now it looks like below when I use the FileInput on the current master/ binder branch, i.e. the nice stapled line is missing.

import panel as pn

pn.config.sizing_mode = "stretch_width"

file_input = pn.widgets.FileInput()

pn.template.FastListTemplate(
    site="Panel",
    title="Download and Upload CSV File",
    main=[
        file_input,
    ],
).servable()

I can see that the fast_bokeh.css file needs to change from

input[type=file] {
    background: transparent;
    width: 100%;
    height: 100px;
    border: 3px dashed var(--neutral-outline-rest);
    border-radius: calc(var(--corner-radius) * 1px);
    text-align: center;
    margin: auto;
}
input[type=file][disabled]:hover {
  cursor: not-allowed;
  border-color: var(--neutral-outline-rest);
}
input[type=file]:hover {
  border-color: var(--neutral-outline-hover);
}

input[type=file]:active {
  border: 3px dashed var(--neutral-outline-active);
}

to

.bk-root input[type=file] {
    background: transparent;
    width: 100%;
    height: 100px;
    border: 3px dashed var(--neutral-outline-rest);
    border-radius: calc(var(--corner-radius) * 1px);
    text-align: center;
    margin: auto;
}
.bk-root input[type=file][disabled]:hover {
  cursor: not-allowed;
  border-color: var(--neutral-outline-rest);
}
.bk-root input[type=file]:hover {
  border-color: var(--neutral-outline-hover);
}

.bk-root input[type=file]:active {
  border: 3px dashed var(--neutral-outline-active);
}

Fixed on binder branch.

This indeed has been fixed for a while.
