In T359636, one of the approaches to handle content overflow is to use ellipses when it is important to maintain a consistent component height. This will be needed for Buttons (T337865), Selects (T347621), and other components like ChipInputs. The suggested method for providing the full text content to users is through a Tooltip.

We need to ensure that we can reliably automatically apply ellipses truncation in these situations. We also need to ensure using a Tooltip to display the full Button label does not present any accessibility issues, particularly on touchable screens where the hover is not possible.

There has been feedback in T337865#9861972 that the content overflow approach should avoid using ellipses in Buttons, which we can evaluate once we have a working version.

Acceptance Criteria

• Determine if ellipsis truncation can be reliably used for truncation in Codex components
• Determine if a Tooltip can reliably be rendered when text is truncated using an ellipsis, including on touch devices
• Decide if using ellipses for Button labels is still the best UX
