Issue in Firefox and float type column

[Leo F]

In columns of type float the backspace key does not work, but only in Firefox.

Here is one of your demos:

Click to edit the freight column, and then try to use backspace.

Can this be resolved without changing column type or using a custom editor?

Thanks for reporting Firefox and float dataType issue, it would be fixed in next release.

For now, this issue can be resolved by specifying filterKeys: false in editModel.

Now this issue is not there in the new version. But due to some technical issue we are not switching to latest version. Tell me how to fix these issue in the older version.
We cant make filterKeys:false, because it will allow characters.
