How to target the object and include the before text?

For example, in jsx, the each attribute of element are split by <space>.
But Treesitter doesn't include the separator(space).

When I delete this textobj(test={true}), the `' before is still there.
This is correct, but it is inconvenient.

Then I need to delete that space manually.

So, is there any to target the attribute, but also include the space(one or more) before?

and here's my config now.

; jsx attributes
(jsx_self_closing_element attribute: (_) @attribute.outer)
(jsx_element open_tag: (_ attribute: (_) @attribute.outer))

Start from the JSX attribute query patterns shown in the issue and inspect how captured @attribute.outer nodes are turned into text-object ranges. Check how preceding whitespace is handled for deletion, then verify the behavior on the JSX examples described in the issue. Done means targeting an attribute can include its preceding space without requiring a separate deletion.
