[-- Attachment #1.1: Type: text/plain, Size: 9628 bytes --]

Consider the following code when using typescript-ts-mode or tsx-ts-mode:

     try {

     } catch (err) {

     }

     try {

     } catch (err: Error) {

     }

In neither of the above cases, the code "err" will not be highlighted as 
a variable.

Attached is a patch which fixes this.
