md-progress-linear: CSS conflicts with md-autocomplete

[Barnabas]

When the linear progress bar displays while the autocomplete is in the middle of a query, the progress bar appears to the right of the input box, like this:

I found this on Chrome 43.0.2357.81 and in Angular Material 0.9.7.

The root cause is that the selector which sets CSS position to "relative" for the indeterminate progress bar (md-progress-linear[md-mode="indeterminate"]) is more specific than the progress bar in the autocomplete control (md-autocomplete md-autocomplete-wrap md-progress-linear).

The rewrite of the animation for indeterminate mode introduced this CSS property (1d478eb, line 67), but I believe that it's unnecessary. The "relative" position of the child md-container should be sufficient. An alternate fix is to make the CSS selector in the autocomplete CSS more specific, as in md-autocomplete md-autocomplete-wrap md-progress-linear[md-mode="indeterminate"].

In the meantime, the workaround is to add the following CSS:

md-autocomplete md-autocomplete-wrap md-progress-linear[md-mode="indeterminate"] {
    position:absolute;
}
