When the label is not able to resize in a given layout and calls to
`setIndent` or `setMargin` further reduce the space available, the text
should be squeezed. Qt does not send a resize event which would notify
us to squeeze the text. Therefore, these functions need
reimplementations adding manual calls to `squeezeTextToLabel`.
This fixes the autotest `testChrome` failing only on the CI (see T6982).
