End-of-video detection broken on Invidious

[mattfbacon]

This code causes on error on Invidious which makes it impossible to start a segment.

SponsorBlock/src/content.ts

Lines 2066 to 2079 in 8eb7c0c

	function getRealCurrentTime(): number {
	// Used to check if replay button
	const playButtonSVGData = document.querySelector(".ytp-play-button")?.querySelector(".ytp-svg-fill")?.getAttribute("d");
	const playButtonSVGDataNew = document.querySelector(".ytp-play-button")?.querySelector("path")?.getAttribute("d");
	const replaceSVGData = "M 18,11 V 7 l -5,5 5,5 v -4 c 3.3,0 6,2.7 6,6 0,3.3 -2.7,6 -6,6 -3.3,0 -6,-2.7 -6,-6 h -2 c 0,4.4 3.6,8 8,8 4.4,0 8,-3.6 8,-8 0,-4.4 -3.6,-8 -8,-8 z";
	const replaceSVGDataNew = "M11.29 2.92C14.85 1.33 18.87 1.06 22";
	if (playButtonSVGData === replaceSVGData || playButtonSVGDataNew.startsWith(replaceSVGDataNew)) {
	// At the end of the video
	return getVideoDuration();
	} else {
	return getCurrentTime();
	}
	}

Obviously these selectors don't work on Invidious. Not sure if the problem that is being worked around here (getCurrentTime wrong when at end-of-video) even exists on Invidious, but in any case the following patch works to avoid the exception:
