[Phenomenon]
It has been confirmed that, under certain conditions, content may not be saved on the designer screen after updating the version of the browser you are using.
[Occurrence condition]
This may occur depending on the combination of the version of your browser and IM-BloomMaker.
* Target browsers
It has been confirmed that this occurs when updating to the following versions or later:
- Microsoft Edge version 151 or later
- Google Chrome version 151 or later
* The version in which this occurs depends on the operating specifications of each browser.
* Occurrence conditions for IM-BloomMaker
A: If the following elements are placed on the main page:
- Standard component: The “Progress Bar” element in the “Parts” category is placed on the main page
- Standard component: The "Audio Embedding" element in the "Parts" category is placed on the main page
B: If you are using custom elements or pseudo-elements in CSS.
- Writing CSS that adds pseudo-elements (::before, ::after) to input tags / progress tags using custom elements or CSS editors
* The conditions under which this issue occurs in IM-BloomMaker are still under investigation, and there may be other conditions that trigger it besides those listed above.
[Cause]
This is a bug in the "html2canvas" library used by IM-BloomMaker.
The cause is that due to updates in each browser, the library can no longer convert elements that include pseudo-elements (::before, ::after).
[Temporary workaround]
* If the occurrence condition A applies
Please place the relevant element on a page other than the main page.
If you want to display the element upon initial display, please use the "Container Page Embedding" element to display it.
Alternatively, set a dummy page as the main page and use the action item "Open page {page}" to make it appear upon initial display.
* If the occurrence condition B applies
Please ensure that the CSS is applied only to the application screen.
By adding ".im-hichee-production-mode" to the CSS selector, it is possible to apply the CSS only to the application screen.
Example:
```
.im-hichee-production-mode input::before {
/* Pseudo-element decoration */
}
```
It is also possible to avoid this by specifying CSS that disables pseudo-elements.
Example:
```
.im-hichee-designer-mode input::before {
content: none !important;
}
```
* Please note that there are the following restrictions regarding style specification using the CSS editor, so please use this as a temporary measure only.
