When integrating Chart.js with the 'responsive' option set to true, the library relies on the parent container's dimensions to calculate the canvas size. A common conflict occurs when the parent element uses CSS Grid or absolute positioning without a defined height, leading to the chart rendering at 0px height or triggering an infinite resize loop.
The internal animation loop monitors for size changes, but it requires a bounding box to exist at the moment of initialization. If the container's dimensions are determined dynamically via asynchronous content or late CSS application, the chart may fail to synchronize its internal state with the actual DOM layout.

How does Chart.js handle initialization scenarios where the parent container reports zero dimensions during the first constructor call?
- Is there a specific configuration to prevent recursive resize events when the container uses a flex-based layout?
