描述

Bug Description:

The goal is to have better (more uniform) support for icons present in the sidepanels, namely for docked editors. Currently, when problems.decorations.tabbar.enabled is enabled, editors with warnings or errors are not displayed correctly or consistently for different file-icon themes:

seti: Screenshot_2021-02-12_11-02-36

Steps to Reproduce:

start the application and make sure that problems.decorations.tabbar.enabled is enabled
open a json editor, create error markers and dock the editor in the sidepanel
change the file-icon theme (F1 + Preferences: File Icon Theme)

研究方向: Investigate the sidepanel tab decoration code in the Theia repository, particularly around the problems.decorations.tabbar.enabled feature. Look at how file icons are applied to docked editors and compare behavior across different icon themes. Check relevant source files in packages/editor and packages/sidepanel for inconsistencies.
