add new customSnippet to snippetsByCategory.snippet_custom. It will trigger the reactivity. We probably not need to reload the page

[sobo-odoo]

In the end, I simply reloaded the snippets by calling load, because I still need to get the snippet html after the call (in order to be able to drop it afterwards), which is not easy to retrieve from the orm call
So the easiest was to just reload the snippets 🙂

I made the changes (see diff + other diff improving the rest of the of the test) 🙂

t-on-pointerdown.stop="() => {}" (Why you need to do it ?)

[sobo-odoo]

Because the sidebar or the container (don't remember which one) does something on pointerDown, which means that every time I clicked on the input, this click was canceled by this something, so I could not write in it
But I think this is temporary, when we will make the style,... of the sidebar correctly, maybe this could be removed ? I will see at that time 👍

this is because of prettier 🥲 I cannot add it back 😬

I made the changes (see diff) 🙂
I only clean for save the clone now (so I removed the savepoint) and so I fixed the clean_for_save_handlers in order to be consistent and to take into account the root element too (first commit) 🙂
