❓ Quick question, with the test HTML provided in the PR description, should the option to "Ungroup block" work? If I tap it, it doesn't do anything 😅
|
Yeah, it should ungroup the block. I'll take a look 👀, thanks for sharing it ! |
I managed to reproduce it. Looks like there's a bug related to the ungrouping logic used in the |
That sounds good to me, thank you for investigating it! |

What?
Fixes an error related to pasting content with complex structures that leads to hitting the maximum call stack size specified in Hermes (reference).
Why?
Fixes wordpress-mobile/WordPress-Android#18750 and wordpress-mobile/gutenberg-mobile#6123.
How?
The issue was produced due to the fact that the implementation of
Node.containswas recursive. This function is used as part of the pasting functionality, so when a deeply nested structure is processed, the call stack could grow until it reaches the limit and crashes the editor.gutenberg/packages/react-native-editor/src/jsdom-patches.js

The solution proposed is to replace the implementation with a non-recursive approach. In fact, the implementation has been copied from the original polyfill we use in WordPress core for the function
Node.contains(reference 1, reference 2, reference 3). This polyfill is no longer used but we keep a reference (reference).deepFilterNodeListis also recursive, hence we might still get the error after applying this fix. However, it's likely that would happen in very edge cases.Testing Instructions
