Description

Hi,

I'm having problems to adjust content of a tab to 100% of height of md-tab-group

For example:

<md-tab-group style="background-color: lightblue; height: 100%">// this works all bk is blue
<md-tab label="Info" style="background-color: indianred; height: 100%">//not work
<div style="background-color: yellow; height: 100%"></div>//with % not work, with px works
</md-tab>
</md-tab-group>

My problem is that md-tab-group expands his height to total of height. But the atribute height of md-tab doesn't fit to 100% of md-tab-group.

Because of that the content, even if I set the height to 100% it doesn't fit to 100% of height

If I set thet height attribute of the <div> to for example 500px it works correctly

I have this problem since I added <!doctype html> to my index.html

Versions: Beta.5 Angular 4

What would be doing wrong?

Research direction
Investigate the CSS height inheritance issue in the Angular Material tab group. Look at the `md tab group` and `md tab` component styles, especially how they handle percentage heights. The issue may be related to the parent not having an explicit height or a missing height on intermediate DOM elements. Check for any CSS containment or display properties affecting height calculation. Also consider the impact of the HTML5 doctype on box sizing and rendering mode.
