[OpenSRP 2] The cursor constantly moves to the beginning of the word/number when one tries to fill details in the registration form

[f-odhiambo]

Describe the bug
The cursor constantly moves to the beginning of the word/number when one tries to fill details in the registration form.

To Reproduce
Steps to reproduce the behavior:

1. Login to the app
2. Click on Add new Patient in the Drawer
3. In the registration form; observe the cursor when you are filling in the details of any field.

RESULTS:
When one is filling in the details of any field; the the cursor constantly moves to the beginning of the word/number. This causes inaccuracies in filling the correct details. One has to also select the end of the word/ number to continue typing.

Expected behavior
The cursor should always be at the end of the last thing typed unless selected otherwise.

See below video under Quantity restocked in the stock inventory page while trying to restock a commodity.
for ECBIS this seems to only impact the Quantity restock

@f-odhiambo @dubdabasoduba After investigation it seems that the issue of the cursor moving to the beginning when typing in the Quantity Restocked field can be traced to the calculated-expression for the Pending stock adjustment quantity question.

The defiition for the Quantity Restocked can be found below

    {
      "extension": [
        {
          "url": "http://hl7.org/fhir/StructureDefinition/minValue",
          "valueInteger": 0

      "initial": [
        {
          "valueInteger": 0
        }
      ]
    }

As can be seen the Quantity Restocked field is not part of the items used in the calculated-expression above. The interesting thing is that when the Quantity Restocked linkId is added to the calculated-expression the bug does not occur.
