Commit 8c53ac6
setup an experiment to prevent double measure of text (#44120)
Summary:
Pull Request resolved: #44120
changelog: [internal]
Prevent measuring the same text twice in `ParagraphShadowNode`.
The current implementation calls `TextLayoutManager::measure` twice for a single `ParagraphShadowNode`. The first time to measure the node for Yoga. The second time inside `ParagraphShadowNode::layout`. I think the original author counted on the cache inside of `TextLayoutManager` to deal with this, but this is not always the case and `TextLayoutManager::measure` is called with two different available widths, leading to cache miss and fills the cache faster.
