Keep focus on measure after hiding an instrument

When hiding an instrument with a measure selected (even in another staff), if the instrument presented extensive horizontal space requirement differences (see note below), the focus seems to change to the same horizontal position, presumably the same page number, instead of the same measure, which may be very distant from the originally selected measure. This is annoying and confusing.

Suggestion: keep focus on measure number instead of horizontal distance from the beginning of the score. If no measure is selected, use as reference the measure closer to the center of the score window.

Note: Hiding an Instrument is necessary when adding fake instruments to customize (humanize) playback of trills o rolls, for instance. They require many notes, that's why the length change is considerable
