IntelliSense Include suggestion leaves extra '>' symbol

[ImaginaryExponent]

Environment

• OS and Version: Windows_NT x64 10.0.19044
• VS Code Version: 1.79.0-insider (user setup), commit 506cd5056d875ccdbea2e9a41ba7b9f19103d599
• C/C++ Extension Version: v1.16.0

Bug Summary and Steps to Reproduce

Bug Summary:
While editing #include <|> lines, if IntelliSense provides suitable hint, applying that hint via Tab or Enter sometimes introduces an extra closing angle bracket.

Steps to reproduce:

1. Create an mepty 'proj' folder for the project.
2. In the 'proj' folder create an empty main.cpp file.
3. In the 'proj' folder create a 'fld1' sub-folder.
4. In the 'proj/fld1' folder create a 'fld2' sub-folder.
5. In the 'proj/fld1' subfolder create an empty hdr1.h.
6. In the 'proj/fld1/fld2' subfolder create an empty hdr2.h.
7. In the 'proj/main.cpp' type #include <fld1/fld2/hdr2.h>
8. Try editing the #include line to #include <fld1/hdr1.h>. Use IntelliSense suggestion when it is offered.
9. Using IntelliSense suggestion inserts selected item as #include <fld1/hdr1.h>>. Note the second >.

Expected behavior:
The > symbol is not inserted where not needed.

Most frequently this happens when the new #include <> path is shorter than the existing one. Like if some string IntelliSense composes is one character too long and copies extra > or on the contrary, one character too short and does not see the existing >.

Thank you for reporting this issue. It didn't always happen for me. When it did, it seemed to be because there was a . (for the .h) between the cursor and the closing >.

Fix available in pre-release https://github.com/microsoft/vscode-cpptools/releases/tag/v1.17.0.

Tested on the v1.17.0 preview, looks good.
