Incomplete presentation of warnings in editor when build tasks are set to use 'shared' panels, reveal policy 'silent'.

Environment

• OS and Version: Windows_NT x64 10.0.19045
• VS Code Version: 1.86.1 (system setup)
• C/C++ Extension Version: v1.18.5, also reproduced in many early versions, like v1.12.4.
• If using SSH remote, specify OS of remote machine: Ubuntu 23.10. ONLY REPRODUCED VIA SSH REMOTE, not locally.
• GCC Version: 13.2.0 (Ubuntu 13.2.0-4ubuntu3)

Bug Summary and Steps to Reproduce

Bug Summary

When I compile C++ code on remote machines (connected through 'Remote - SSH') multiple times, warnings thrown by GCC could not be displayed properly in editor. As number of times I compile the same piece of code increases, warnings shown correctly in editor vanish one by one.

Steps to reproduce

1. Connect to a remote Ubuntu machine with 'C/C++' extension installed via 'Remote - SSH'.
2. Insert the following content in .vscode/tasks.json:

{
	"version": "2.0.0",
	"tasks": [
		{
			"label": "sysGCC Compile - Debug",
			"type": "cppbuild",
			"command": "g++",
			"args": [
				"${file}",
				"-o",
				"${fileBasenameNoExtension}",
				"-Wall",
				"-Wconversion",
				"-Wshadow",
				"-Wextra",
				"-g",
				"-std=c++14"
			],
			"presentation": {
				"echo": true,
				"reveal": "silent",
				"focus": false,
				"panel": "shared",
				"showReuseMessage": false,
				"clear": true
			},
			"options": {
				"cwd": "${fileDirname}"
			}
		}
	]
}

3. Add a new C++ source file. Here is an example. Its content doesn't matter — one may replace it with some other code that also triggers many warnings, but no errors.
4. Run task 'sysGCC Compile - Debug' multiple times. Do not open the panel, as we set presention > reveal policy as silent. Pay attention to warnings shown in the editor at the first time the file is compiled. Then run the task again for a couple of times. Each time, only a subset of warnings shown are preserved; the others disappeared.
5. Open the panel, take a look at the warnings thrown by GCC, output to shell. One may find that only a subset of them are shown in the editor.
6. Press any key to terminate the shell, close the panel and run the task again. All warnings are shown correctly. One may goto step 4 and repeat the process above.
7. Edit .vscode/tasks.json, replace section presentation with

"presentation": {
	"echo": true,
	"reveal": "always",
	"focus": false,
	"panel": "shared",
	"showReuseMessage": false,
	"clear": true
}

or whatever configuration that does not use a shared, unrevealed panel, for instance

"presentation": {
	"echo": true,
	"reveal": "silent",
	"focus": false,
	"panel": "new",
	"showReuseMessage": false,
	"clear": true
}

8. Now run the task multiple times. The issue does not occur anymore.

This bug could not be reproduced on my local environments, neither on Windows 10 nor Ubuntu 23.10.

Expected behavior

Show all warnings correctly in editor, no matter how section presentation of a task is configured.

Other Extensions

Only a language pack and 'Remote - SSH' are activated, locally and remotely.

Additional context

No response

Reproduce the issue using the .vscode/tasks.json presentation settings, Remote - SSH, GCC, and the C/C++ extension; compare repeated task runs with shared/silent panels against new or revealed panels. Trace how task output becomes editor diagnostics, using c_cpp_properties.json and the supplied C/C++ logs as context. Done means all compiler warnings remain visible in the editor across repeated runs.
