Split measures report wrong beat information in status bar
I can't confirm this was different before the fractions were introduced in version 3.1 I think so I'm not sure it's a regression.
When you split measures, the fraction for the actual duration of the measure is reduced. This causes the reported beat of a selected notes to be reported incorrectly at times.
For example, split a 4/4 measure into two 2 beat measures and the actual duration will be reported as 1/2. Enter 2 1/4 notes into this measure and select the second note and it will be reported as being on beat 1.5.
When a measure is split, the current time signature should be taken into account. The example above should have two measures with an actual duration of 2/4 rather than the reduced 1/2. This is not always possible. If a 4/4 measure were split on beat 1.5 there is no choice but to set the actual durations as 3/8 and 5/8 since fractions do not support numerators that are not whole numbers.
This issue was found while researching and fixing #310223: Select>More... does not select notes on "Same beat" of short measures which currently relies on the actual duration reduction so this needs to not break that PR.
