Setting page ID starting from digit

If I register a setting page with ID starting from digit - when I click on the name - page doesn't show (I'm using name=id):

It looks like this is a html thing you can't have a html id starting with a number

[id='1800number_box'] {
/* does work */
}

it's the bootstrap code that needs to be fixed for this to work: twbs/bootstrap#31099
so we will update the docs to tell developers to not use ids that start with a digit. PSDK-160

Probably fixed by twbs/bootstrap#35566

Sounds like we need to update bootstrap in the core. Thanks for pointing this out. Tracking the update of bootstrap in HS-1593
