Inconsistent behaviour of nested sections

[sfranzen]

Describe the bug
Suppose I have a test case with a structure like the following:

TEST_CASE("Nesting")
{
    SECTION("A") {
        SECTION("1") SUCCEED();
        SECTION("2") SUCCEED();
    }
    SECTION("B") {
        SECTION("1") SUCCEED();
        SECTION("2") SUCCEED();
    }
}

Upon selecting the test case and section on the command line, I get the following results:

• ./test Nesting: All four assertions are executed;
• ./test Nesting -c A: Only A1 is executed;
• ./test Nesting -c B: B1 and B2 are executed.

Expected behavior
./test Nesting -c A should execute all subsections of section A.

Reproduction steps
See description.

Platform information:

• Compiler+version: GCC v9.1.1
• Catch version: v2.8.0, v2.9.1

Thanks for the report.

Upon further investigation, this was introduced by #1492 and affects all sections that are not the last section, in other words, in this

TEST_CASE("Nesting")
{
    SECTION("A") {
        SECTION("1") SUCCEED();
        SECTION("2") SUCCEED();
    }
    SECTION("B") {
        SECTION("1") SUCCEED();
        SECTION("2") SUCCEED();
    }
    SECTION("C") {
        SECTION("1") SUCCEED();
        SECTION("2") SUCCEED();
    }
}

Only "C" is unaffected.

Thanks, that has given me somewhere more specific to look, and it looks like an easy fix.
