symbol info does not popup

## Information

info on cursor shows in echo line only, not in balloons. (I'm using Plug to load ale.) Thanks in advance.

**VIM version**

nvim v0.10.1
Build type: Release

Operating System: Windows 10

## What went wrong

I've been using ale for years and ale never pops automatically no matter what combinations I set.

## Reproducing the bug

1. open a source file, such as flow.go
2. move cursor to a function or a variable
3. the declaration of it shows in echo line only, not a popupwin
4. :ALEHover shows the popupwin
