Description

Description

Completions requests are not always sent to the debug adapter after every character typed.
Reproduction steps:

  1. Run the Mock Debug Adapter
  2. Launch the "Debug readme.md" debug configuration
  3. Start typing "item" in the debug console.

I expect the debug adapter completions to show up after every character typed, but sometimes, they do not.

This seems to be related to whether there is another source of completions or not. In the mock debug adapter, there's some suggestions for markdown formatting which show up, but in my custom debug adapter, history suggestions have caused this issue. Subsequently, with my custom debug adapter, if the "debug.console.historySuggestions" setting is turned off, then it works as expected. The debug adapter completions also show up properly if the completions window is closed and reopened.
