Slider with a fractional step in the input seems to kill the CPU.

[cristiano-belloni]

my directive template:

// [...]
'<material-slider>' +
    '<input type="range" ng-model="fx_data.ampli_level" min="0" max="3" step="0.25">' +
 '</material-slider>' +
// [...]

This (and any other fractional value) makes the page unresponsive, and the CPU in Chrome's task manager goes up to > 100%.
Instead, step="1" seems ok.
