"My filters" displayed filters and actually used filters can be different in some cases (timing issue when saving?).

Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

After saving filter A in normal window and filter B in incognito, uBO will show filter A in My filters, but apply filter B.

A specific URL where the issue occurs

Steps to Reproduce

1. Open Dashboard in normal window and type example.com in My filters
2. Open Dashboard in Incognito window and type example.net in My filter
3. Switch to normal window
4. Save filter in normal window by Ctrl+S
5. Quickly switch to Incognito window (place mouse cursor over it on taskbar before previous point to make it faster)
6. Save filter in Incognito window by Ctrl+S
7. Refresh dashboard in both widows

Expected behavior:

• Last filter win OR
• Both windows have it's own filter saved
• Filters work as expected when "example" pages opened in new tabs

Actual behavior:

• Incognito window keeps .net filter
• Normal window My filters editor updates to .net filter (after Dashboard was refreshed)
• .net filter is applied in Incognito window when tried in new page
• Normal window applies .com filter despite .net being visible in My filters

confuse main and incognito storage

There is only one storage for both normal and incognito. Both instances of uBO uses the same storage.
