Description

Description

Duplicate editors for untitled and file schemes for the same path. When the user calls the "showTextDocument" API (with "untitled" scheme and a non existing path ) a new tab is opened ( as expected). The user can edit the file and click 'CTRL+s' to save the file ( and the file is saved --> also as expected). But when the user then go to file-->open and navigate to the saved file and choose to open it --> a new tab is opened ( and we have duplication of the same tab ).

Contributor guide

Research direction
Investigate the editor tab creation logic in Theia, specifically how showTextDocument handles 'untitled' and 'file' schemes for the same path. Trace the flow when saving an untitled document and then opening the saved file via File > Open to understand why a duplicate tab is created.
