We noticed an issue with our Numeric TextBox after a recent upgrade on Chrome. We're currently on Version 73.0.3683.86 (Official Build) (64-bit), the latest version at the time of writing. Our setup has a grid using a TreeView as an editor template. The TreeView, in turn, uses a NumericTextBox inside its item template. I've prepared a working demo that illustrates the issue. If you click on the last column of the grid, expand the TreeView and click on one of the NumericTextboxes, you will see that it loses the focus as soon as you click on it. As a result, it's impossible to input anything into those fields. Any other browsers don't have this issue.
We had a lot of issue reports from our clients this week so we're pretty sure it's a recent update from Chrome. Please let me know if you need further clarification. This is a fairly serious issue for us as it's affecting one of the main functionalities of our web application. If you can provide a temporary workaround before the proper fix comes out, that'd be great.
