Description

@CDDelta

Steps to Reproduce

  1. Usefile_selector.openFile() and pick a file ~500-700MB on web.
  2. Read it into memory usingreadAsBytes().

Expected results:

The file data can be loaded into memory.

Browsers can support buffer sizes of ~2GB so a ~500-700MB file should not fail.file_picker_cross is able to load files larger thanfile_selector_web.

Actual results:

ARangeError: Array buffer allocation failed will be thrown.
