typescript 1.5 beta in webstorm 10.0.2, get an error: TS2304-Cannot find name 'DataView' #2998

Description

@raregrass

What steps will reproduce the problem?

  1. Use custom typescript 1.5 beta compiler.
  2. Type a code snippet: let a: typeof DataView.
  3. Get an error: Error:(1, 15) TS2304: Cannot find name 'DataView'.

What is the expected result?
It should be right.

What happens instead?
Get an error.

Please provide any additional information below.
When I use bounded typescript 1.4 compiler and the new typescript 1.5 alpha compiler, everything is OK. I don't know where I should put this issue, so I put it both in webstorm and typescript issue track platform. Please check and tell me what should I do.

                              typescript 1.5 beta in webstorm 10.0.2, get an error: TS2304-Cannot find name 'DataView' #2998

                              Description

                              @raregrass

                              What steps will reproduce the problem?

                              1. Use custom typescript 1.5 beta compiler.
                              2. Type a code snippet: let a: typeof DataView.
                              3. Get an error: Error:(1, 15) TS2304: Cannot find name 'DataView'.

                              What is the expected result?
                              It should be right.

                              What happens instead?
                              Get an error.

                              Please provide any additional information below.
                              When I use bounded typescript 1.4 compiler and the new typescript 1.5 alpha compiler, everything is OK. I don't know where I should put this issue, so I put it both in webstorm and typescript issue track platform. Please check and tell me what should I do.
