Bundle product with hundreds of options takes minutes to save and timeout (with inventory enabled)

[santerref]

Preconditions (*)

1. Magento version 2.4.3
2. Inventory enabled
3. Bundle product with a lot of options (200 to 500)

Steps to reproduce (*)

1. Enable the inventory
2. Create a bundle product with 200+ options (children)

Expected result (*)

1. Product save quickly as usual
2. The indexes are updated for 201 products

Actual result (*)

1. The plugin ReindexSourceItemsAfterSaveBundleSelectionPlugin of the module module-inventory-bundle-product-indexer is called after each saveChild of \Magento\Bundle\Model\LinkManagement and reindex all the options and the main product. That means for a bundle product with 200 options, the 200 options get reindexed 200 times ! 200 reindex requests of 201 products.
2. The save takes more than 3 to 5 minutes and the server timeout. We can't save our bundle products.
