Vladimir Golovnev 2b20d5b260 Fix startup performance on Qt5
Use more appropriate container (QList) for resume data queue buffer.
QVector in Qt5 has poor performance of the first element taking operation,
which is used to process the resume data queue. In Qt6, QVector is just an
alias for QList, so there was no problem there.

PR #18387.
Fixes #18341.
