Undefined variable for escaped variables

[MrBIN89]

Describe the bug
Example of code

*** Settings ***
Force Tags    vscode
*** Variables ***
@{DEFAULT_LIST}     @{EMPTY}

*** Test Cases ***
Import Variables Should Not Cause Undefined Variables
    @{SUITE_LIST_1} =    Set Variable    ${DEFAULT_LIST}
    Set Suite Variable    \@{SUITE_LIST_1}    one    two
    Set Suite Variable    @{SUITE_LIST_2}    three   four
    Should Be Equal    ${SUITE_LIST_1}[0]    one
    Suite Variable Should Be Defined In Keyword

*** Keywords ***
Suite Variable Should Be Defined In Keyword
    Should Be Equal    ${SUITE_LIST_1}[0]    one
    Should Be Equal    ${SUITE_LIST_2}[0]    three

Causes undefined variable for SUITE_LIST_1 in the next keyword, though SUITE_LIST_2 is defined properly

Expected behavior
Both variables are defined properly and don't cause errors

Versions:

• OS: Windows 10
• Robot Framework Version: 4.1.3
• Robot Framework Language Server Version: v0.43.2
• Client Version: VSCode 1.66

This should be fixed in the 0.43.5 pre-release (please test it -- if everything is ok a new stable release should be done -- hopefully tomorrow).
