Tests modifying attributes of a TextTrackCue


** Test initial values.
RUN(textCue = cues.getCueById('1'))
EXPECTED (textCue.startTime == '0') OK
EXPECTED (textCue.endTime == '1') OK
EXPECTED (textCue.pauseOnExit == 'false') OK
EXPECTED (textCue.vertical == '') OK

EXPECTED (textCue.line == '-1') OK
EXPECTED (textCue.position == 'auto') OK
EXPECTED (textCue.size == '100') OK
EXPECTED (textCue.align == 'center') OK

** Modify cue values.
RUN(textCue.startTime = 1.1)
EXPECTED (textCue.startTime == '1.1') OK

RUN(textCue.endTime = 3.9)
EXPECTED (textCue.endTime == '3.9') OK

On setting, the text track cue writing direction must be set to the value ... is a case-sensitive match for the new value, if any. If none of the values match, then the user agent must instead throw a SyntaxError exception.

On setting, if the text track cue snap-to-lines flag is not set, and the new value is negative or greater than 100, then throw an IndexSizeError exception.

On setting, if the new value is negative or greater than 100, then throw an IndexSizeError exception. Otherwise, set the text track cue text position to the new value.

EXPECTED (textCue.position == '11') OK

On setting, if the new value is negative or greater than 100, then throw an IndexSizeError exception. Otherwise, set the text track cue size to the new value.

EXPECTED (textCue.size == '57') OK

On setting, the text track cue alignment must be set to the value ... is a case-sensitive match for the new value, if any. If none of the values match, then the user agent must instead throw a SyntaxError exception.
