[EN DateTime V2] Not all phrases of a form [day abbreviation][number] (e.g. "Mon 13th") are consistently recognized

[apolya01]

Describe the bug Shortened day-name + Date phrases are not consistently recognized/resolved. Examples of phrases:

Mon 13th Tue 13th Wed 13th Thu 14th Fri 14th Sat 14th Sun 14th

Expected behavior All phrases conforming to this format should be recognized and resolved in a consistent manner - ideally with the entire phrase as one date - not either only the day part, or the day part and number part as separate entities.

Sample input/output recognizeDateTime("Mon 14th")

(2) [{…}, {…}]
0:{start: 0, end: 2, resolution: {…}, text: 'mon', typeName: 'datetimeV2.date'}
end:2
resolution:{values: Array(2)}
values:(2) [{…}, {…}]
[[Prototype]]:Object
start:0
text:'mon'
typeName:'datetimeV2.date'
[[Prototype]]:Object
1:{start: 4, end: 7, resolution: {…}, text: '13th', typeName: 'datetimeV2.date'}
end:7
resolution:{values: Array(2)}
values:(2) [{…}, {…}]

recognizeDateTime("Tue 14th")

(1) [{…}]
0:{start: 0, end: 2, resolution: {…}, text: 'tue', typeName: 'datetimeV2.date'}
end:2
resolution:{values: Array(2)}
values:(2) [{…}, {…}]

@aitelint Could you validate that this doesn't happen in .NET? Is this a case of date and DOW not matching?

ok, I will check

@tellarin, yes these patterns work fine in .NET. Only "Mon 13th" gives problems because it is caught as "on 13th", I have pushed a fix for that. This is not a case of date and DOW not matching, for this pattern the recognizer returns the first (last) date which agrees with DOW.
