Tooltip text overflow

Hello there,

first of all I'm using MDB 4.6.0 but it is not possible to choose the version.

Then to the main problem. In my project I am using some tooltips. Some of them have a very long content and the problem is, that the tooltip box do not have the correct height. Only the first words are in the box.
So I tested a little bit to fix the problem and I found out that this is only a problem with md-tooltip and md-tooltip-main. md-tooltip-email works well. I have some examples for you.

md-tooltip:
Template:

template: '<div class="tooltip md-tooltip">' +
        '<div class="tooltip-arrow md-arrow"></div>' +
        '<div class="tooltip-inner md-inner"></div>' +
    '</div>'

Result:

md-tooltip-main:
Template:

template: '<div class="tooltip md-tooltip-main">' +
        '<div class="tooltip-arrow md-arrow"></div>' +
        '<div class="tooltip-inner md-inner-main"></div>' +
    '</div>'

md-tooltip-email:
Template:

template: '<div class="tooltip md-tooltip-email">' +
        '<div class="tooltip-arrow md-arrow"></div>' +
        '<div class="tooltip-inner md-inner-email"></div>' +
    '</div>'

Have I missed some option for md-tooltip and md-tooltip-main or is that not possible with them? Or maybe a bug in the calculation of the height?
For now I will use md-tooltip-email, but I like the md-tooltip-main style more and would be very happy if this will work too.

Kind regards
