Text cells show as dirty changes when reverting values to empty string

Hi there,

We've encountered a bug with the dirty state for text columns in Bryntum Grid 5.6.4.

The issue is that text columns (with no specified type) without a value show as dirty / detect changes when the value is updated (set to a non empty string value) and then reverted to an empty string.

This is only a present when clearing values and does not occur when reverting a value that is not an empty string.

Reproducible in the cell edit demo example https://www.bryntum.com/products/grid/examples/celledit/ by adding a new column to the columns array, e.g:

columns : [
    { text : 'Test' }
],

This doesn't look to affect other column types, tested the same scenario with date / number columns and they clear the dirty state as expected.

Reproduction steps:

• Add a new text column to the grid
• Set a value on a text cell with no value
• Revert the text cell's value to no value (empty string)
• The cell displays as dirty in its original state

Is this a known issue and do you have any suggestions for a workaround?

Thanks, Callum
