1322110 - HTML5 input type='number' does not accept patterns defined

Status: RESOLVED DUPLICATE of bug 1253606

(Core :: DOM: Core & HTML, defect)

Description

[Olivier Houdas]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161129173726

Steps to reproduce:

I'm using the following input area in my form:
<input type='number' pattern='[0-9]+([\.,][0-9]+)?' step='any' lang='fr'>
and I'm trying to type "1.2" in FF French under a French OS


Actual results:

Firefox 50 indicates "Veuillez saisir un nombre." ("Please enter a number.")


Expected results:

Firefox should have accepted my input, as it matches the pattern regex.
Note that 
<input type='number' pattern='[0-9]+([\.,][0-9]+)?' step='any' lang='en-us'>
does accept both "1.2" and "1,2" inputs as valid, as expected.
