why your lib dont throw any error with ts ?!

[jonlepage]

why your libs dont trhow error with ts ?
example

if i replace title by <div><div/> the ts server let this pass !
but at compilation i get the error !
And vscode intelisence seem also broken and acting weird !

do i need to active something ? of i missed something !
why ts dont alarm me when am using wrong type with your libs , but work for all others libs ?
Do i have special setting to setup with your lib ?
thanks
