Pedal connection with multiple voices

I experienced a situation where consecutive pedal lines did not align correctly by default. They usually connect when the first line ends at the same beat the second line starts, but there was a slight offset in this case.

I used two voices in the staff to which the pedal line was attached. The voices were separated by an interval of a second, forcing the noteheads to be vertically offset. I noticed two cases : when the lower voice lasts until the end of the measure, the pedal line behaves properly; when the lower voice last for a shorter time, the pedal lines are misaligned.

Here is a simple demonstration of both cases in order, from left to right. Notice how the pedal changes on the third beat of each measure behave differently according to the content of the lower staff.

As far as I know, having the same setup in the upper voice does not trigger the problem. It seems that only the lower staff affects the line, which makes sense since the line is attached to that particular staff.

I managed to reproduce this in MuseScore 2.3.2, in 3.0.0 and in the latest nightly build (MuseScoreNightly-201901032201-master-c38df7a-x86_64), all on Ubuntu 18.10; see attachments for MuseScore files.

Does anyone have an idea why this is happening? Should a bug report be filed for this?
