## Background: The native DOM Parser can perform poorly on some older devices, this approach is faster on newer devices but is considerably better on older devices. This PR replaces the usage of the DOM Parser for DASH, MSS, VTT and TTML. The draw back of this approach that it does not include any validation at the cost of better performance.
