I was going to report this today, but you beat me to it.
I finally figured out what was happening today.
This started happening as early as last Friday.
Some machines would look fine, while others are missing the date icon on a date field with a date picker.
Of course, if you had plenty of screen space, and your field was already "wide", then you wouldn't even notice this.
Fields of 165px show a tiny sliver of the icon, making it still useful. But 130px would have no icon. Its some math/rounding error somewhere. As the field gets wider, the error diminishes and all looks normal.
NOTE: It is def. not an aware issue. I examined the XML that generates forms (in chrome) and also the Elements & Styles code in chrome explorer and it was identical EXCEPT for the width of the Date <input date control.
This is related to the latest version of Chrome 127.XXX (plus Edge, firefox is affected)
The issue
If you put a date field on the screen, that’s either 12 symbols or 120 pixels wide, let’s say, not overly large but barely wide enough to fit,
Then some algorithm somewhere in either Chrome or Kendo is oversizing the <input > portion.
If you want 125 pixels for your date control, the input field is actually 100, and the icon is 25.
But after the update, the field ends up being the full width, 125 pixels, and it’s covering the date picker.
Using an example of a field set to 125 pixels,
In chrome explorer if you select the input field, you can add a statement width: 100px
And the date picker icon will be revealed.
And it’s fully functional.
This was very perplexing.
As I had two customers report “missing calendars" on the same day.
But it wasn’t happening to me on my office Mac Chrome, and it wasn’t happening on three other windows PCs I tried.
15 users in one office were affected, 5 not affected… Now we realize it’s because they have not relaunched chrome to apply the update, or they do not have automatic updates enabled.
Solution number 1.
Is to roll back chrome. Instructions on Google.
Solution number 2.
Modify your app and widen the date field on screens.
I had to set all my Fields to Width 180px (20 symbols is not enough) to where they look normal again, although the date control is grotesquely long/wide. But it was easier than rolling back PCs to prev version.
