Template style settings: colour boxes extremely narrow and php warnings

[ggieling]

Description

1. The colour boxes <input type="color" name="tpl[__text__]" id="tpl____text__" ...> in the template style settings in dokuwiki are extremely narrow when working in the bootstrap3 template.
2. The template style settings page shows warning messages. When opening the settings page in the wiki the below message appears below the colour boxes area.
   Warning: Trying to access array offset on value of type null in /srv/http/won1/content/inc/parserutils.php on line 151
   After opening as popup additional warnings appear above the coulor boxes area.
   Warning: Trying to access array offset on value of type null in /srv/http/won1/content/inc/toolbar.php on line 270 (twice)
   Warning: Trying to access array offset on value of type null in /srv/http/won1/content/inc/toolbar.php on line 271 (twice)

Steps to reproduce

1. install bootstrap3 addon
2. activate bootstrap3 addon
3. goto admin -> Template Style Settings

Steps to solve

1. revert to dokuwiki template

I expected the colour boxes to be visible in standard size as in the default dokuwiki template (box size 54x22) and the page to not display any warnings

colour boxes are extremely narrow (box size 3x20) and the warnings appear

This can be fixed by excluding inputs of type color from getting the form-control class

C:\server\Apache24\htdocs\dokuwiki\lib\tpl\bootstrap3\script.js
line 144
jQuery('input, select, textarea')
.not('[type=submit], [type=reset], [type=button], [type=hidden], [type=image], [type=checkbox], [type=radio], [type=color]')

C:\server\Apache24\htdocs\dokuwiki\lib\tpl\bootstrap3\Template.php
line 1502
if (!in_array($elm->type, ['submit', 'reset', 'button', 'hidden', 'image', 'checkbox', 'radio', 'color'])) {
$elm->class .= ' form-control';

I had to clear the cache C:\server\Apache24\htdocs\dokuwiki\data but I don't know whether its needed
