Currently, if I pass a JS string equals to

"This is my \"ametys\" description"

the tooltip will display "This is my "

If I want to display the right tooltip text, I must pass the string in JS

"This is my "ametys" description"

which means that if it is an i18n string, it should be declared as

<message key="MY_KEY">This is my &amp;quot;ametys &amp;quot; description</message>

in the XML catalogue

Automatically replacing the double quotes characters should be more user-friendly for non-developpers who write some i18n keys in messages_xx.xml catalogues
