Important: #100135 - Remove cookie warning in ext:felogin
See forge#100135
Description
The cookie warning message in ext:felogin is never shown, since it depends on conditions, which will never be met. The cookie warning message can also be considered superfluous, since a similar message is already shown, if authentication was not successful.
Code affecting the non-working cookie warning message has therefore been
removed from ext:felogin. TYPO3 users should remove code from custom templates,
which depend on the {cookie variable.
