TTML Subtitle lines with ampersand skipped during playback
While previewing the timing of created TTML subtitles, we discovered a strange behavior during playback. All subtitle linens containing an ampersand character (no matter if "&", "&"& (closed);") were skipped. Other entities (like """) worked in TTML correctly. This issue with missing lines with an ampersand character is related only to the TTML subtitle format, the lines were displayed worked correctly in SRT and WebVTT version. Tested both in 3.0.0 and 4.0.0 with the same result.
