During an onchange, fields read from database are validated again. This causes
an infinite loop with HTML fields since Odoo 16 because we're revalidating a
value we're reading from the database, which triggers a sanitisation check,
which fetches the original value, etc etc.
Even if the functional bug only appears in 16.0 and above, the root cause is
also present in 15.0 so this commit targets 15.0
steps to reproduce (in 16 or next versions):
- Change Marc Demos's access rights Website = Restricted Editor
- Bypass HTML Field Sanitize = Off
- Inventory / Products / Product Variants
- Studio on the Sales tab and add website_description under Website Sequence
- Go to product [E-COM07] Large Cabinet and fill in the newly added website description
- Log out and log in as marc demo
- Navigate back to [E-COM07] Large Cabinet product variant and try to re-order the vendors on the purchase tab
- Error
