Checkbox unselecting in tree grid is not taking place for specific steps

[Tuariq]

Hi Team,

Observing this strange issue where checkbox unselecting in tree grid is not getting reflected on UI for specific steps when grid selection mode is 'Both'

Steps:

1. Click on header checkbox to select all checkboxes at once
2. On any particular row, click inside check box cell just beside the checkbox element

Actual result:

It is observed that on UI the checkbox of row is seen checked when in actual that row gets unchecked (See the header check box it changes from checked to dash)

Expected results:

The row should be shown unchecked

Note:

It happens only when selection mode is 'Both'. It is to be noted that this particular mode is needed since in real scenario we need cell and row click events

Please find attached file for sample code where issue is reproducible by above steps. It also includes a video sample inside folder named 'issue-video'.

Hi Dhinesh G,

I checked the provided response. Although the UI seems fixed, but I am still not getting the internal 

checkboxChange() event fired when row is unselected using above steps.
