Ignore display.max_rows in DataFrame.to_html(escape=False)

[flying-sheep]

If escape=False is specified, this dataframe fill fail horribly…

df = DataFrame(data={
    'test': ['<a href="http://reallylongurlthateasilyislongerthan50characters.htm">short linkname</a>'],
})

…as the <td><a href="http://reallylongurlthateasilyislongertha...</td> will be broken HTML, and the a tag is closed by the closing td tag.

i propose that display.max_rows is ignored for cells that contain unescaped HTML tags (i.e. at least one < character)
