Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0 Build ID: 20161204030210 [Affected versions]: Nightly 53.0a1 [Affected platforms]: All platforms: Windows 10 x 64,Ubuntu 15.04, Mac OS X [Steps to reproduce]: 1.Launch Nightly 53.0a1 with a new profile 2.Set "dom.forms.datetime" pref to True in about:config 3.In the URL bar enter "data:text/html, <input type="time" value="08:30" step="600" min="8:30" max="12:30">" 4.Enter by keyboard a value that is outside the preset step (e.g. 08:33) 5.Click outside the input box [Expected result]: The input box margins should be red and the error message "Please select a valid value.The two nearest valid values are 08:20 and 08:30." should be displayed as a bubble message with red text. [Actual result]: The input box margins are red but no error message is displayed.
This is the same behavior like for other input fields which get validated, e.g. opening data:text/html, <input type="email"> and entering an invalid email address and clicking somewhere will not show the message. At the moment, the error message is only visible as tooltip if the mouse gets moved over the input field. See also bug 630495.
