Search button icon vertically misaligned with the other icons

[dbitouze]

As pointed out by the joined minimal documentation using PyData Theme, making use of:

html_theme_options = {
    "navbar_persistent": ["search-button"],
}

leads to a search button icon vertically misaligned with the other icons:

With:

html_theme_options = {
    "navbar_persistent": ["search-button","search-field"],
}

we get:

which shows how search-button and search-field differ in terms of the vertical alignment of icons.
