TMSS-1001: Issue in displaying timeline tooltip when time exceeds the current display duration.

TMSS-917: refactored the parallel LBA calibrator and target observations into one task with one specification with two parts (for the calibrator and the target). This enables us to have a single parent task for each subtask again, which is preferrable

TMSS-918: Removed using resolved_schema in task view as it is not loaded properly in JSON Editor. After testing properly need to enable it.
