decimal number entry broken with locale "Denmark (English)"

[iexos]

Just trying out Grist with a free account and stumbled into this disturbing bug:

My locale was set to Denmark (English) automatically due to my system settings. Now I cannot enter decimal numbers, any , or . will be discarded and the number will be interpreted as an integer.

This is bad enough to make it unusable, but making matters worse: Clicking to edit any existing (imported) cell and clicking out without typing anything will also do this conversion, changing my numbers unintentionally. Automatic text-to-number conversion by changing the column type is broken as well.

Changing my locale manually to United States (English) solved the issue.
