1.2.0

• Fix issue preventing wrap detection when flex items have unequal heights
• Several performance optimizations:

  • Added debouncing: The ResizeObserver callback is now debounced with a 16ms delay (approximately matching a 60fps refresh rate), which reduces the frequency of calculations during resize operations.

  • Added dimension caching: The library now stores the previous dimensions of each flex container and skips recalculations if the dimensions haven't changed, which avoids unnecessary processing.

  • Reduced layout thrashing: Added rect caching to avoid multiple costly calls to getBoundingClientRect() for the same elements during a single calculation cycle.

  • Optimized DOM operations: Added the updateAttributeEfficiently helper function which only modifies attributes when necessary, reducing DOM updates and potential reflows.

  • Improved wrap-reverse detection: The algorithm for grouping items by their position now looks for nearest matches within a tolerance range, which is more efficient than the previous approach.

  • Batch calculations: Measurements are now batched together to minimize the number of reflows caused by reading layout properties.
