Actual Results

The focus indicator of  "Split" button in the "Split Issu" modal fails the minimum color contrast requirements with its background color. 
FG: #3A8EFF
BG: #0055CC
Contrast ratio: 2:1

This will make it difficult for people with low vision and color blindness to identify the focus indicator for the user interface controls that have insufficient contrast.

Expected Results

The contrast ratio between the foreground color of focus indicator and its background color should be sufficient.

Ensure that the color contrast of focus indicator for all user interface controls is 3:1 with the foreground and background color.

In this case, provide spacing between the focus indicator and the button.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
