Popover can't show number as content

[Kirill89]

If data-content attribute specified as number (like data-content="123456"), will be an error.

Error text: Uncaught Error: TOOLTIP: Option "content" provided type "number" but expected type "(string|function)"..

Demo on jsfiddle.

There are, in if it is the number should be taken to operate. Add space in the back, if you want to use to "123456".

@design8383 your solution works well, but looks like a workaround.

I think it's a bug because data-content attribute can't be anything except string.

@Kirill89 Your 're right. This bug is not a solution. A simple tip that can only be used.

I don't think it's related to #18641.
#20210 seems to be the appropriate fix as the problem come from an explicit restriction on the format of the data-content here https://github.com/twbs/bootstrap/pull/20210/files#diff-e9010e9ff0ddb6c88e5442067e24aa1fL37
