Math widget: Option math_priority appears broken

[Chealer]

I have never used option math_priority before, but it seems to be ineffective in 2.27.8 if I try to get rows to be computed after columns. In the attached testcase, the table's last cell is empty, unless the

$("#tableauGroupes").trigger('recalculate');

line is enabled. The cell is based on values to its left, which are based on values from columns above. Therefore, unless there is confusion,

math_priority : [ 'col', 'row', 'above', 'below' ],

should allow calculating the totals before calculating the last cell, which uses custom function pourcentageAssurance. Yet, when the function executes, it is given an array of zeroes, which means the total line still has dummy values (string "Chargement", which is converted to 0).

This happens in 2 browsers on 2 tested (Firefox 50 and Google Chrome 54).

Sorry. HTML attachments are not allowed, and this is invalid.

I reported the issue which caused me to report this invalid ticket in ticket #1319.
